geoDTN: Geographic Routing in Disruption Tolerant Networks
2011

1 -- 5
In this paper we present a disruption tolerant routing algorithm based on geographic location information, which improves upon the hop count compared to the current state of the art by up to a factor of three in large scale human networks. Leveraging only the history of geographic movement patterns in the two-hop neighborhood, our algorithm is able to perform well in the absence of knowledge of social interaction between nodes and without detailed future schedule information.
Representing previously visited locations as probability distributions encoded in an efficient vector, we formalize a heuristic for efficiently forwarding messages in disruption tolerant networks, implement a framework for comparing our approach with the state of the art, and evaluate key metrics, such as hop count and delivery rate, as well as energy consumption and battery depletion fairness on real world data. We are able to outperform the state of the art in human mobility based networks considerably in terms of energy usage per node, thereby extending data network availability further into areas devoid of otherwise necessary communication infrastructure.

Secure Resolution of <prt>End-Host</prt> Identifiers for Mobile Clients

Many efforts of the network research community focus on the introduction ofa new identifier to relieve the IP address from its dual role of end-hostidentifier and routable locator. 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.

A direct interpretation of the term Internet of Things refers to the use of standard Internet protocols for the human-to-thing or thing-to-thing communication in embedded networks. Although the security needs are well-recognized in this domain, it is still not fully understood how existing IP security protocols and architectures can be deployed. In this paper, we discuss the applicability and limitations of existing Internet protocols and security architectures in the context of the Internet of Things. First, we give an overview of the deployment model and general security needs. We then present challenges and requirements for IP-based security solutions and highlight specific technical limitations of standard IP security protocols.

Perfect Difference Sets for Neighbor Discovery

1--6
We present an energy efficient neighbor discovery framework that enables Linux and TinyOS based systems to discover and connect to neighbors via IEEE 802.11 and IEEE 802.15.4, which are only available sporadically. Using quorum schemes, we schedule on and off times of the wireless transmitters, to guarantee mutual discovery with minimum power given a specific latency requirement. Neighbor discovery is fundamental to intermittently connected networks, such as disruption and delay tolerant networks and optimizing it, can lead to significant overall energy savings.
Using perfect difference sets, our results indicate that we reduce the latency by up to 10 times at a duty cycle of 2% compared to the state of the art. We further define and characterize our neighbor discovery scheme with respect to fairness for asymmetric energy scenarios. Using these results, we allow energy-harvesting applications to adjust neighbor discovery based on their current energy requirements as a well defined trade-off.

We present FootPath, a self-contained, map-based indoor navigation system. Using only the accelerometer and the compass readily available in modern smartphones we accurately localize a user on her route, and provide her with turn-by-turn instructions to her destination. To compensate for inaccuracies in step detection and heading estimation, we match the detected steps onto the expected route using sequence alignment algorithms from the field of bioinformatics. As our solution integrates well with OpenStreetMap, it allows painless and cost-efficient collaborative deployment, without the need for additional infrastructure.

Demo: Establishing Mobile Ad-Hoc Networks in 802.11 Infrastructure Mode
2011

89-90
Mobile Ad-Hoc Networks (MANETs) rely on the 802.11 ad- hoc mode to establish communication with nearby peers. In practice, this makes MANETs hard to realize. While 802.11-compliant mobile devices implement the ad-hoc mode on the hardware layer, the software layer typically does not implement support for ad-hoc networking in terms of ad-hoc routing and name resolution protocols. Modern mobile operating systems, such as Android and iOS, even hide the inherent ad-hoc functionality of the wireless card through restrictions in the OS. In contrast to this, support for the 802.11 infrastructure mode is a commodity.
We propose establishing ad-hoc networks using the 802.11 infrastructure mode. In MA-Fi (Mobile Ad-Hoc Wi-Fi), a small core of mobile router nodes (RONs) provides infrastruc-ture mode network access to mobile station nodes (STANs). As RONs also act as a station in infrastructure networks of other RONs, MA-Fi achieves multi-hop communication between RON and STAN devices in the overall network.
We show the creation and operation of mobile ad-hoc networks using MA-Fi. We focus on mobility of RONs and STANs as well as topology control in the overall network.

Efficient Power Management Using Out-of-Band Signaling
2011

77-80
A tremendous amount of energy is wasted today, because computing devices are left running all the time even though they are needed only sporadically. Especially in office environments many devices (e.g., printers) are very rarely turned off, because they need to be available from time to time and because it is inconvenient having to switch them on and off manually. Existing solutions, such as Wake-on-LAN (WoL), provide support for managing the power consumption of the network devices remotely using an always-on data channel. However, these solutions are inefficient, because power to the network interface has to be maintained even when the host system is asleep just to ensure remote accessibility.
We propose a Wireless Sensor Network (WSN) based out-of-band signaling architecture for network interfaces which minimizes the systems’ power consumption during the large idle periods when nobody is using them. This is done by separating the data and control channels on the Internet-enabled devices using a low-power out-of-band signaling channel based on battery driven, energy scavenging devices. Unlike existing solutions, which only allow parts of the system to go in sleep modes, our architecture allows the whole system, including the main power supply, to be shut down.
Our initial investigation indicates a significant reduction in energy consumption of devices during idle times compared to the existing in-band signaling mechanisms such as WoL.

QoE in Collaborative Wireless Local Area Networks

One of the major’s contributions of Collaborative Wi-Fi Networks is to provide a widely distributed Wi-Fi access network in a low cost and ubiquitous way. In order to promote the participation of more actors (both Wi-Fi providers and users) and the success of this kind of emerging solutions is important to satisfy the expectations that the user has regarding the network and the services, increasing the Quality of User Experience (QoE).
As one might expect the wireless nature of the Collaborative Wi-Fi Networks imposes a set of challenges those have to be addresses in order to guarantee the QoE that the users are expecting.
In this talk, we outline research challenges encountered to improve the overall experience of the user of Collaborative Wi-Fi Networks. Our approach is to study the effect of the user´s perception firstly modifying the way that the user picks the Access Point during the Wireless Association. We highlight how an association based on the selection of the Access Point with the largest RSSI does not guarantee the satisfaction of the expectations of the users. Second, we explain how avoiding duplicate data packets downloaded in the same BSS, improving the throughput of the BSS and the QoE.

Scalable Symbolic Execution of Distributed Systems
2011

333-342
Recent advances in symbolic execution have proposed a number of promising solutions to automatically achieve high-coverage and explore non-determinism during testing.
This attractive testing technique of unmodified software assists developers with concrete inputs and deterministic schedules to analyze erroneous program paths.
Being able to handle complex systems' software, these tools only consider single software instances and not their distributed execution which forms the core of distributed systems.
The step to symbolic distributed execution is however steep, posing two core challenges: (1) additional state growth and (2) the state intra-dependencies resulting from communication.
In this paper, we present SDE—a novel approach enabling scalable symbolic execution of distributed systems.
The key contribution of our work is two-fold.
First, we generalize the problem space of SDE and develop an algorithm significantly eliminating redundant states during testing.
The key idea is to benefit from the nodes' local communication minimizing the number of states representing the distributed execution.
Second, we demonstrate the practical applicability of SDE in testing with three sensornet scenarios running Contiki OS.

rfc6253
The Certificate (CERT) parameter is a container for digital
certificates. It is used for carrying these certificates in Host Identity Protocol (HIP) control packets.
This document specifies the CERT parameter and the error signaling in case of a failed verification.
Additionally, this document specifies the representations of Host Identity Tags in X.509 version 3 (v3) and Simple Public Key Infrastructure (SPKI) certificates.
The concrete use of certificates, including how certificates are obtained, requested, and which actions are taken upon successful or failed verification, is specific to the scenario in which the certificates are used.
Hence, the definition of these scenario- specific aspects is left to the documents that use the CERT parameter.

Floating Content: Information Sharing in Urban Areas
2011

21
Content sharing using personal web pages, blogs, or online social networks is a common means for people to maintain contact with their friends, colleagues, and acquaintances. While such means are essential to overcome distances, using infrastructure services for location-based services may not be desirable. In this paper, we analyze a fully distributed variant of an ephemeral content sharing service, solely dependent on the mobile devices in the vicinity using principles of opportunistic networking.
The net result is a best effort service for floating content in which: 1) information dissemination is geographically limited; 2) the lifetime and spreading of information depends on interested nodes being available; 3) content can only be created and distributed locally; and 4) content can only be added, but not explicitly deleted. First we present our system design and summarize its analytical modeling. Then we perform extensive evaluation for a map-based mobility model in downtown Helsinki to assess the operational range for floating content, which, at the same time also validate the analytical results obtained for a more abstract model of the system.

Runtime Efficient Event Scheduling in Multi-threaded Network Simulation
2011

359-366
Developing an efficient parallel simulation framework for multiprocessor systems is hard. A primary concern is the considerable amount of parallelization overhead imposed on the event handling routines of the simulation framework. Besides more complex event scheduling algorithms, the main sources of overhead are thread synchronization and locking of shared data structures. As a result, the overhead of parallelization may easily outweigh the benefits of parallelization in comparison to classic sequential simulation.
We introduce two efficient event handling schemes based on our parallel-simulation extension Horizon for the OMNeT++ simulator.First, we present a \emph{push-based event handling scheme} to minimize the overhead of thread synchronization and locking. Second, we complement this scheme with a novel \emph{event scheduling algorithm} that significantly reduces the overhead of parallel event scheduling. Lastly, we prove the correctness of our scheduling algorithm. Our evaluation reveals a total reduction in the event handling overhead of up to 16x when combining both schemes.

draft-garcia-core-security-01
A direct interpretation of the Internet of Things concept refers to
the usage of standard Internet protocols to allow for human-to-thing
or thing-to-thing communication. Although the security needs are
well-recognized, it is still not fully clear how existing IP-based
security protocols can be applied to this new setting. This
Internet-Draft first provides an overview of security architecture,
its deployment model and general security needs in the context of the
lifecycle of a thing. Then, it presents challenges and requirements
for the successful roll-out of new applications and usage of standard
IP-based security protocols when applied to get a functional Internet
of Things.

End-Host Authentication for HIP Middleboxes (Version 4)
2011
draft-heer-hip-middle-auth-04
The Host Identity Protocol [RFC5201] is a signaling protocol for secure communication, mobility, and multihoming that introduces a cryptographic namespace. This document specifies an extension for HIP that enables middleboxes to unambiguously verify the identities of hosts that communicate across them. This extension allows middleboxes to verify the liveness and freshness of a HIP association and, thus, to secure access control in middleboxes.
