In practice, however, supply chains face severe technical challenges, especially regarding security and privacy. In this work, we consolidate studies from supply chain management, information systems, and computer science from 2010--2021 in an interdisciplinary meta-survey to make this topic holistically accessible to interdisciplinary research. In particular, we identify a significant potential for computer scientists to remedy technical challenges and improve the robustness of information flows. We subsequently present a concise information flow-focused taxonomy for supply chains before discussing future research directions to provide possible entry points. information flows; data communication; supply chain management; data security; data sharing; systematic literature review internet-of-production https://www.comsys.rwth-aachen.de/fileadmin/papers/2024/2024-pennekamp-supply-chain-survey.pdf ACM 0360-0300 10.1145/3606693 1 JanPennekamp RomanMatzutt ChristopherKlinkmüller LennartBader MartinSerror EricWagner SidraMalik MariaSpiß JessicaRahn TanGürpinar EduardVlad Sander J.

However, the handling of sensitive information, in terms of (i) internal company data and (ii) the underlying algorithm to compute the benchmark, demands strict (technical) confidentiality guarantees—an aspect that existing approaches fail to address adequately. Still, advances in private computing provide us with building blocks to reliably secure even complex computations and their inputs, as present in industry benchmarks. In this paper, we thus compare two promising and fundamentally different concepts (hardware- and software-based) to realize privacy-preserving benchmarks. Thereby, we provide detailed insights into the concept-specific benefits. Our evaluation of two real-world use cases from different industries underlines that realizing and deploying secure information systems for industry benchmarking is possible with today's building blocks from private computing.

Consequently, it requires a technical infrastructure that can support the agile deployment of these concepts and corresponding high-level applications, which, e.g., demand the processing of massive data in motion and at rest. As such, key research aspects are the support for low-latency control loops, concepts on scalable data stream processing, deployable information security, and semantically rich and efficient long-term storage. In particular, such an infrastructure cannot continue to be limited to machines and sensors, but additionally needs to encompass networked environments: production cells, edge computing, and location-independent cloud infrastructures. Finally, in light of the envisioned WWL, i.e., the interconnection of production sites, the technical infrastructure must be advanced to support secure and privacy-preserving industrial collaboration. To evolve today’s production sites and lay the infrastructural foundation for the IoP, we identify five broad streams of research: (1) adapting data and stream processing to heterogeneous data from distributed sources, (2) ensuring data interoperability between systems and production sites, (3) exchanging and sharing data with different stakeholders, (4) network security approaches addressing the risks of increasing interconnectivity, and (5) security architectures to enable secure and privacy-preserving industrial collaboration. With our research, we evolve the underlying infrastructure from isolated, sparsely networked production sites toward an architecture that supports high-level applications and sophisticated digital shadows while facilitating the transition toward a WWL.

Digital shadows enable a more comprehensive understanding and monitoring of processes on shop floor level. Thus, process information becomes available between decision levels, and the aforementioned criteria regarding quality, cost, or safety can be included in control decisions for production processes. The contextual data for digital shadows typically arises from heterogeneous sources. At shop floor level, the proximity to the process requires usage of available data as well as domain knowledge. Data sources need to be selected, synchronized, and processed. Especially high-frequency data requires algorithms for intelligent distribution and efficient filtering of the main information using real-time devices and in-network computing. Real-time data is enriched by simulations, metadata from product planning, and information across the whole process chain. Well-established analytical and empirical models serve as the base for new hybrid, gray box approaches. These models are then applied to optimize production process control by maximizing the productivity under given quality and safety constraints. To store and reuse the developed models, ontologies are developed and a data lake infrastructure is utilized and constantly enlarged laying the basis for a World Wide Lab (WWL). Finally, closing the control loop requires efficient quality assessment, immediately after the process and directly on the machine. This chapter addresses works in a connected job shop to acquire data, identify and optimize models, and automate systems and their deployment in the Internet of Production (IoP).

This paper investigates the association of standardisation engagement with firms'performance as indirect evidence of a sub-optimal level of market standardisation activities. Anecdotal evidence has it that firms can benefit from engagement in standardisation activities, but large quantitative studies on this topic are rather scarce. Based on a large innovation survey, this paper implements matching models to compare outcomes of firms with similar features but different standardisation activities. The outcomes of interest are several measures of innovation and growth. Standardisers and non-standardisers are matched onto a rich set of control variables. Firms engaged in standardisation have better innovation performance than firms with no such activities. However, the results for the performance measures are rather mixed, showing no association or negative association with labour productivity measures. Heteroscedasticity-based instruments mitigate possible endogeneity issues. These results can be interpreted as indirect evidence of low standardisation activity in the market, possibly due to long payback periods and appropriability issues of the standardisation investment. 10.1007/s10961-022-09951-z 1 Cesare Antonio FabioRiillo KaiJakobs article 2022_brauner_iop ACM Transactions on Internet of Things 2022 5 1 3 2 The Industrial Internet-of-Things (IIoT) promises significant improvements for the manufacturing industry by facilitating the integration of manufacturing systems by Digital Twins. However, ecological and economic demands also require a cross-domain linkage of multiple scientific perspectives from material sciences, engineering, operations, business, and ergonomics, as optimization opportunities can be derived from any of these perspectives. To extend the IIoT to a true Internet of Production, two concepts are required: first, a complex, interrelated network of Digital Shadows which combine domain-specific models with data-driven AI methods; and second, the integration of a large number of research labs, engineering, and production sites as a World Wide Lab which offers controlled exchange of selected, innovation-relevant data even across company boundaries. In this article, we define the underlying Computer Science challenges implied by these novel concepts in four layers: Smart human interfaces provide access to information that has been generated by model-integrated AI. Given the large variety of manufacturing data, new data modeling techniques should enable efficient management of Digital Shadows, which is supported by an interconnected infrastructure. Based on a detailed analysis of these challenges, we derive a systematized research roadmap to make the vision of the Internet of Production a reality.

AIS messages are transmitted as broadcasts to nearby ships and contain, among others, information about the identification, position, speed, and course of the sending vessels. AIS can thus serve as a tool to avoid collisions and increase onboard situational awareness. In recent years, AIS has been utilized in more and more applications since it enables worldwide surveillance of virtually any larger vessel and has the potential to greatly support vessel traffic services and collision risk assessment. Anomalies in AIS tracks can indicate events that are relevant in terms of safety and also security. With a plethora of accessible AIS data nowadays, there is a growing need for the automatic detection of anomalous AIS data. In this paper, we survey 44 research articles on anomaly detection of maritime AIS tracks. We identify the tackled AIS anomaly types, assess their potential use cases, and closely examine the landscape of recent AIS anomaly research as well as their limitations. automatic identification system; AIS; anomaly detection; maritime safety; maritime security; maritime surveillance https://www.comsys.rwth-aachen.de/fileadmin/papers/2022/2022-wolsing-aistracks.pdf https://www.mdpi.com/2077-1312/10/1/112 en 10.3390/jmse10010112 1 KonradWolsing LinusRoepert JanBauer KlausWehrle article 2022-jakobs-ieeetem IEEE Transactions on Engineering Management 2022 1-12 Common standards are essential for Information and Communication Technologies (ICT). Several studies suggest that (almost) all standardization working groups (WGs) are dominated by large firms and small and medium-sized enterprises (SMEs) and are typically marginalized. However, SMEs account for around 99% of all enterprises in the EU; their active participation in the standardization process would thus be crucial to develop ICT standards that meet the needs of the vast majority of their users. This article first discusses the current situation of SMEs in ICT standardization and the associated issues. Second, it conducts an econometric analysis to investigate the drivers of the use of ICT standards and engagement in ICT standardization based on a large and representative survey from Luxembourg. Regardless of their size, firms that actually and consciously deploy ICT standards in their core business are much more prepared to participate in standards-setting actively than those that do not. The article also proposes a way to exploit this correlation. The resulting implications for standards-setting organizations and policymakers are discussedn. 10.1109/TEM.2022.3226121 1 Cesare Antonio FabioRiillo KaiJakobs inproceedings 2021-kunze-spin-tracker 2021 12 7 15–21 https://www.comsys.rwth-aachen.de/fileadmin/papers/2021/2021-kunze-spin-tracker.pdf ACM Proceedings of the 2021 Workshop on Evolution, Performance and Interoperability of QUIC (EPIQ '21) 9781450391351 10.1145/3488660.3493804 1 IkeKunze ConstantinSander KlausWehrle JanRüth inproceedings 2021-krude-nfp-pred 2021 12 7 maki https://www.comsys.rwth-aachen.de/fileadmin/papers/2021/2021-krude-nfp-pred.pdf ACM The 17th International Conference on emerging Networking EXperiments and Technologies (CoNEXT '21) 978-1-4503-9098-9/21/12 10.1145/3485983.3494842 1 JohannesKrude JanRüth DanielSchemmel FelixRath Iohannes-HeorhFolbort KlausWehrle inproceedings 2021-sander-shardingrevisited 2021 11 2 legato /fileadmin/papers/2021/2021-sander-sharding-revisited.pdf https://arxiv.org/abs/2110.14239 ACM Proceedings of the Internet Measurement Conference (IMC '21) Internet Measurement Conference 2021 02.11.21 - 04.11.21 978-1-4503-9129-0/21/11 10.1145/3487552.3487832 1 ConstantinSander LeoBlöcher KlausWehrle JanRüth inproceedings 2021_reuter_demo 2021 9 14 Website fingerprinting (WFP) attacks on the anonymity network Tor have become ever more effective. Furthermore, research discovered that proposed defenses are insufficient or cause high overhead. In previous work, we presented a new WFP defense for Tor that incorporates multipath transmissions to repel malicious Tor nodes from conducting WFP attacks. In this demo, we showcase the operation of our traffic splitting defense by visually illustrating the underlying Tor multipath transmission using LED-equipped Raspberry Pis.

Due to a competitive environment, this process imposes strong privacy needs, as leaked business secrets can have devastating effects on participating companies. Consequently, related work proposes to protect sensitive input data of companies using secure multi-party computation or homomorphic encryption. However, related work so far does not consider that also the benchmarking algorithm, used in today's applied real-world scenarios to compute all relevant statistics, itself contains significant intellectual property, and thus needs to be protected. Addressing this issue, we present PCB — a practical design for Privacy-preserving Company Benchmarking that utilizes homomorphic encryption and a privacy proxy — which is specifically tailored for realistic real-world applications in which we protect companies' sensitive input data and the valuable algorithms used to compute underlying key performance indicators. We evaluate PCB's performance using synthetic measurements and showcase its applicability alongside an actual company benchmarking performed in the domain of injection molding, covering 48 distinct key performance indicators calculated out of hundreds of different input values. By protecting the privacy of all participants, we enable them to fully profit from the benefits of company benchmarking. practical encrypted computing; homomorphic encryption; algorithm confidentiality; benchmarking; key performance indicators; industrial application; Internet of Production internet-of-production https://www.comsys.rwth-aachen.de/fileadmin/papers/2020/2020-pennekamp-company-benchmarking.pdf https://eprint.iacr.org/2020/1512 HomomorphicEncryption.org Proceedings of the 8th Workshop on Encrypted Computing & Applied Homomorphic Cryptography (WAHC '20), December 15, 2020, Virtual Event Virtual Event December 15, 2020 978-3-00-067798-4 10.25835/0072999 1 JanPennekamp PatrickSapel Ina BereniceFink SimonWagner SebastianReuter ChristianHopmann KlausWehrle MartinHenze inproceedings 2020_delacadena_trafficsliver 2020 11 12 1971-1985 Website fingerprinting (WFP) aims to infer information about the content of encrypted and anonymized connections by observing patterns of data flows based on the size and direction of packets. By collecting traffic traces at a malicious Tor entry node — one of the weakest adversaries in the attacker model of Tor — a passive eavesdropper can leverage the captured meta-data to reveal the websites visited by a Tor user. As recently shown, WFP is significantly more effective and realistic than assumed. Concurrently, former WFP defenses are either infeasible for deployment in real-world settings or defend against specific WFP attacks only. To limit the exposure of Tor users to WFP, we propose novel lightweight WFP defenses, TrafficSliver, which successfully counter today’s WFP classifiers with reasonable bandwidth and latency overheads and, thus, make them attractive candidates for adoption in Tor. Through user-controlled splitting of traffic over multiple Tor entry nodes, TrafficSliver limits the data a single entry node can observe and distorts repeatable traffic patterns exploited by WFP attacks. We first propose a network-layer defense, in which we apply the concept of multipathing entirely within the Tor network. We show that our network-layer defense reduces the accuracy from more than 98% to less than 16% for all state-of-the-art WFP attacks without adding any artificial delays or dummy traffic. We further suggest an elegant client-side application-layer defense, which is independent of the underlying anonymization network. By sending single HTTP requests for different web objects over distinct Tor entry nodes, our application-layer defense reduces the detection rate of WFP classifiers by almost 50 percentage points. Although it offers lower protection than our network-layer defense, it provides a security boost at the cost of a very low implementation overhead and is fully compatible with today’s Tor network.

However, deploying it securely requires a thorough configuration of a wide range of options. Thus, assessing the security of OPC UA deployments and their configuration is necessary to ensure secure operation, most importantly confidentiality and integrity of industrial processes. In this work, we present extensions to the popular Metasploit Framework to ease network-based security assessments of OPC UA deployments. To this end, we discuss methods to discover OPC UA servers, test their authentication, obtain their configuration, and check for vulnerabilities. Ultimately, our work enables operators to verify the (security) configuration of their systems and identify potential attack vectors. internet-of-production, rfc https://www.comsys.rwth-aachen.de/fileadmin/papers/2020/2020-roepert-opcua-security.pdf en University of Tübingen Proceedings of the 1st ITG Workshop on IT Security (ITSec '20), April 2-3, 2020, Tübingen, Germany Tübingen, Germany April 2-3, 2020 10.15496/publikation-41813 1 LinusRoepert MarkusDahlmanns Ina BereniceFink JanPennekamp MartinHenze article 2020_mann_welding_layers Advanced Structured Materials 2020 4 1 125 101-118 A connected, digitalized welding production unlocks vast and dynamic potentials: from improving state of the art welding to new business models in production. For this reason, offering frameworks, which are capable of addressing multiple layers of applications on the one hand and providing means of data security and privacy for ubiquitous dataflows on the other hand, is an important step to enable the envisioned advances. In this context, welding production has been introduced from the perspective of interlaced process layers connecting information sources across various entities. Each layer has its own distinct challenges from both a process view and a data perspective. Besides, investigating each layer promises to reveal insight into (currently unknown) process interconnections. This approach has been substantiated by methods for data security and privacy to draw a line between secure handling of data and the need of trustworthy dealing with sensitive data among different parties and therefore partners. In conclusion, the welding production has to develop itself from an accumulation of local and isolated data sources towards a secure industrial collaboration in an Internet of Production.

However, especially malicious entry nodes, which know the client’s identity, can also observe the whole communication on their link to the client and, thus, conduct several de-anonymization attacks. To limit this exposure and to impede corresponding attacks, we propose to multipath traffic between the client and the middle node to reduce the information an attacker can obtain at a single vantage point. To facilitate the deployment, only clients and selected middle nodes need to implement our approach, which works transparently for the remaining legacy nodes. Furthermore, we let clients control the splitting strategy to prevent any external manipulation.

Enabling a fine-grained sharing and analysis of data among different stakeholders in an automated manner, such a vision of an Internet of Production (IoP) introduces demanding challenges to the communication, storage, and computation infrastructure in production environments. In this work, we present three example cases that would benefit from an IoP (a fine blanking line, a high pressure die casting process, and a connected job shop) and derive requirements that cannot be met by today’s infrastructure. In particular, we identify three orthogonal research objectives: (i) real-time control of tightly integrated production processes to offer seamless low-latency analysis and execution, (ii) storing and processing heterogeneous production data to support scalable data stream processing and storage, and (iii) secure privacy-aware collaboration in production to provide a basis for secure industrial collaboration. Based on a discussion of state-of-the-art approaches for these three objectives, we create a blueprint for an infrastructure acting as an enabler for an IoP.

This makes early detection of depressive symptoms critical in its prevention and management. This paper presents and discusses the development of Psychologist in a Pocket (PiaP), a mental mHealth application for Android which screens and monitors for these symptoms, and–given the explicit permission of the user–alerts a trusted contact such as the mental health professional or a close friend, if it detects symptoms. All text inputted electronically–such as short message services, emails, social network posts–is analyzed based on keywords related to depression based on DSM-5 and ICD criteria as well as Beck's Cognitive Theory of Depression and the Self-Focus Model. Data evaluation and collection happen in the background, on- device, without requiring any user involvement. Currently, the application is in an early prototype phase entering initial clinical validation. fileadmin/papers/2015/2015-bitsch-phealth-piap.pdf Print Blobel, Bernd and Lindén, Maria and Ahmed, Mobyen Uddin IOS Press

While most of the current techniques are limited to research clinics and require excessive set-up, new consumer EEG devices connected to standard, off-the-shelf mobile devices allow us to lift these limitations. This allows neuropsychological assessment and research in mobile settings, possibly even in remote areas with limited accessibility and infrastructure, thus bringing the equip- ment to the patient, instead of bringing the patient to the equipment. We are developing an Android based mobile framework to perform EEG studies. By connecting a mobile consumer EEG headset directly to an unmodified mobile device, presenting auditory and visual stimuli, as well as user interaction, we create a self-contained experimental plat- form. We complement this platform by a toolkit for immediate evalua- tion of the recorded data directly on the device, even without internet connectivity. Initial results from the replication of two Event Related Potentials studies indicate the feasibility of the approach. fileadmin/papers/2015/2015-bitsch-phealth-brain.pdf Print Blobel, Bernd and Lindén, Maria and Ahmed, Mobyen Uddin IOS Press

Lifting these limitations brought about by this artificial set-up would allow us to perform neuropsychological assessments and research in mobile settings or at locations easier accessible to patients, possibly even in remote, hard to access areas. We developed a tablet based mobile framework to present auditory and visual stimuli, capture wireless commercial EEG and screen interaction data, and analyze the recorded data for immediate evaluation, as well as share the data over internet or local opportunistic links. To demonstrate the feasibility of our approach, we successfully replicated the experimental set-up and evaluation pipeline of two existing EEG studies on event-related potentials. This work therefore lays the foundation to further truly mobile brain research and health-care applications. fileadmin/papers/2014/2014-bitsch-extremcom-mobile-eeg-demo.pdf Online Hui, Pan and Lindgren, Anders ACM Proceedings of the 6th Extreme Conference on Communication Galapagos Islands, Ecuador 6th Extreme Conference on Communication August 11-15, 2014 en 978-1-4503-2929-3 1 Jó AgilaBitsch Link RoannRamos DavidOrlea KlausWehrle inproceedings 2014-hummen-delegation 2014 6 30 284-292 iotsec;

This identifier-locator split introduces anew identifier between human readable domain names and routable IPaddresses. Mapping between identifiers and locators requires additionalname mapping mechanisms because their relation is not trivial. Despite itspopularity and efficiency, the DNS system is not a perfect choice forperforming this mapping because identifiers are not hierarchicallystructured and mappings are frequently updated by users. In this paper wediscuss the features needed to resolve flat identifiers to locators in asecure manner. In particular, we focus on the features and the performancethat identifier-locator split protocols require from a mapping system. Tothis end, we consider a mapping system for an identifier-locator splitbased mobility solution and evaluate its performance.

Furthermore, Distributed Hash Tables (DHTs), due to their features, are used more and more for file-sharing and content distribution applications. However, a major weakness of traditional DHTs is the search for stored content, as data is assigned to nodes based on hash functions, and the very nature of hash tables allows only exact pattern matches. We present Cerco, a solution for the problem of range queries by using the principles of order-preserving DHTs and a hierarchically structured P2P approach. To guarantee an efficient routing and load balancing, Cerco uses a dynamic hierarchy of DHTs by creating subrings on demand and two explicit load balancing strategies. Our evaluation shows that Cerco is able to achieve the goals of supporting range queries, logarithmic-hop routing, and efficient load balancing.

So far the distribution of load, caused by the players in these games, is not distributed dynamically. After the launch of a new game, the introduction of new content, during special ingame events, or also during normal operations, players tend to concentrate in certain regions of the game worlds and cause overload conditions. Therefore we propose the use of structured P2P technology for the server infrastructure of the MMOGs to improve the reliability and scalability. Previous work segmented the game work into rectangular areas; however this approach often split a group of players to different servers, causing additional overhead. This work presents a cluster-based Peer-to-Peer approach, which can be used for load balancing in MMOGs or in other virtual worlds. The system is able to dynamically adapt to the current state of the game and handle uneven distributions of the players in the game world. We show through simulation, also with traces from real online games, that the cluster-based approach performs better than the previous P2P-based systems, which split the world in rectangular areas.

Massively multiplayer online games (MMOGs) are becoming increasingly popular today. However, even high-budget titles like World of Warcraft that have gone through extensive betatesting suffer from downtimes because of hard- and software problems. Our approach is to use structured P2P technology for the server infrastructure of MMOGs to improve their reliability and scalability. Such P2P networks are also able to adapt to the current state of the game and handle uneven distributions of the players in the game world. Another feature of our approach is being able to add supplementary servers at runtime. Our system allows using off-the-shelf PCs as infrastructure peers for participation in different game worlds as needed. Due to the nature of the Economy of Scale the same number of hosts will provide a better service than dedicated servers for each game world.

The key space of the so-called Distributed Hash Tables (DHTs) is partitioned and each partition with its keys and values is assigned to a node in the DHT. For data retrieval however, the very nature of hash tables allows only exact pattern matches. We propose Cerco, a simple solution for the problem of range queries by employing a hierarchically structured P2P approach based on the principles of Distributed Hash Tables. We show that a dynamic hierarchy of DHTs with on-demand classification of items can positively influence the response time of queries while maintaining lookup correctness.

Massively multiplayer online games (MMOGs) are becoming increasingly popular today. However, even high-budget titles like World of Warcraft that have gone through extensive beta-testing suffer from downtimes because of hard- and software problems. Our approach is to use structured P2P technology for the server infrastructure of MMOGs to improve their reliability and scalability. Such P2P networks are also able to adapt to the current state of the game and handle uneven distributions of the players in the game world. Another feature of our approach is being able to add supplementary servers at runtime. Our system allows using off-the-shelf PCs as infrastructure peers for participation in different game worlds as needed. Due to the nature of the Economy of Scale the same number of hosts will provide a better service than dedicated servers for each game world.

In this paper we present SARA (Anonymous Overlay Routing Providing Sender And Receiver Anonymity), which enables sender, receiver and relationship anonymity using layered encryption and distributed traffic mixes, similar to a Chaumian Mix. Via IP-datagram service and address virtualization it is fully transparent to applications. Organized as structured Peer-To-Peer system, SARA is highly scalable and fault tolerant. In SARA each communication partner randomly selects a number of nodes from the overlay and concatenates them to an anonymous communication path. The sender selects the head of the path, the receiver builds the tail and publishes this information in the overlay network using an anonymous ID. Via this ID the sender retrieves the tail nodes of the path and concatenates both path section. Layered encryption hides the identities of the sender, receiver and the intermediate nodes. 5.

Although recent research focuses strongly on energy aware applications and operating systems, power consumption is still a limiting factor. Once sensor nodes are deployed, it is challenging and sometimes even impossible to change batteries. As a result, erroneous lifetime prediction causes high costs and may render a sensor network useless, before its purpose is fulfilled. In this paper we present AEON, a novel evaluation tool to quantitatively predict power consumption of sensor nodes and whole sensor networks. Our energy model, based on measurements of node current draw and the execution of real code, enables accurate prediction of the actual power consumption of sensor nodes. Consequently, preventing erroneous assumptions on node and network lifetime. Moreover, our detailed energy model allows to compare different low power and energy aware approaches in terms of energy efficiency.

Distributed hash tables (DHT) are designed for highly scalable, self-organizing, and efficient distribution and lookup of data, whereby data is stored globally persistent. The range of values of the corresponding hash function is partitioned and each interval is assigned to a node of the DHT. Because the assignment of data to nodes is based on hash functions, one assumes that the respective data load is distributed evenly across all participating nodes. However most DHT show difficulties with load balancing as we demonstrate in this paper. As a solution for this problem, we present a new and very simple approach for balancing stored data between peers in a fashion analogous to the dissipation of heat energy in materials. We compare this algorithm with other approaches for load balancing and present results based on simulations and a prototype implementation. This new algorithm improves the distribution of load in DHT without requiring major changes of the DHT themselves. In addition, we show that the fault tolerance of peer-to-peer systems is increased by the proposed algorithm. http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?isnumber=29935&arnumber=1367197&count=128&index=2 Print IEEE Press Proceedings of LCN 2004 – 29th IEEE Conference on Local Computer Networks IEEE Tampa, Florida, USA LCN 2004 – 29th IEEE Conference on Local Computer Networks November 2004 en 0-7695-2260-2 10.1109/LCN.2004.10 SimonRieche LeoPetrak KlausWehrle inproceedings 200410riechehotp2preliability 2004 10 108-113 Peer-to-Peer (P2P) systems are very useful for managing large amounts of widely distributed data. For this purpose Distributed Hash Tables (DHT) offer a highly scalable and self-organizing paradigm for efficient distribution and retrieval of data. Thereby a common assumption of P2P-Systems is, that the participating nodes are unreliable and may fail at any time. Since many of research goes into the design of DHT lookup services, these systems aim to provide a stable global addressing structure. But to storage data reliable in a DHT only few techniques were already developed. However since data has to be stored persistent in the network, it should be retrieved anytime, even if nodes fail. In this work we discuss possibilities to store data fault tolerant in a structured Peer-to-Peer system.

Due to their crucial characteristics – namely scalability, flexibility, and resilience – they are quite interesting for being applied in ad-hoc networks. But, there are plenty of open questions concerning the applicability of Distributed Hash Tables in mobile ad-hoc scenarios: Do new problems arise when both technologies are used together? Are there any synergy effects when both technologies are combined? Are the results and assumptions, made for the infrastructural Internet, still true if a mobile ad-hoc network is used instead? In this paper, we discuss these and further questions and offer some solutions for using Distributed Hash Tables in ad-hoc networks. Print GI. LNI
