Since assembly is considered a main cost driver and accounts for a major part of production time, research focuses on new technologies in assembly. The paradigm of Line-less Mobile Assembly Systems (LMAS) provides a solution for the future of assembly by mobilizing all resources. Thus, dynamic product routes through spatiotemporally configured assembly stations on a shop floor free of fixed obstacles are enabled. In this chapter, we present research focal points on different levels of LMAS, starting with the macroscopic level of formation planning, followed by the mesoscopic level of mobile robot control and multipurpose input devices and the microscopic level of services, such as interpreting autonomous decisions and in-network computing. We provide cross-level data and knowledge transfer through a novel ontology-based knowledge management. Overall, our work contributes to future safe and predictable human-robot collaboration in dynamic LMAS stations based on accurate online formation and motion planning of mobile robots, novel human-machine interfaces and networking technologies, as well as trustworthy AI-based decisions.

By mobilization of multipurpose resources and dynamic planning, Line-less Mobile Assembly Systems (LMASs) offer organizational reconfigurability. By proposing a holarchy to combine LMASs with the concept of an Internet of Production (IoP), we enable LMASs to source valuable information from cross-level production networks, physical resources, software nodes, and data stores that are interconnected in an IoP. The presented holarchy provides a concept of how to address future challenges, meet the requirements of shorter lead times, and unique lifecycle support. The paper suggests an application of decision making, distributed sensor services, recommender-based data reduction, and in-network computing while considering safety and human usability alike.

Among them, semi-static ICIC offers a balanced trade-off between applicability and system performance. The power allocation per resource block and cell is adapted in the range of seconds according to the load in the system. An open issue in the literature is the question how fast the adaptation should be performed. This leads basically to a trade-off between system performance and feasible compu- tation times of the associated power allocation problems. In this work, we close this open issue by studying the impact that different durations of update times of semi-static ICIC have on the system performance. We conduct our study on realistic scenarios considering also the mobility of mobile terminals. Secondly, we also consider the implementation aspects of a semi-static ICIC. We introduce a very efficient implementation on general purpose graphic processing units, harnessing the parallel computing capability of such devices. We show that the update periods have a significant impact on the performance of cell edge terminals. Additionally, we present a graphic processing unit (GPU) based implementation which speeds up existing implementations up to a factor of 92x.

This technology is expected to be handled by domain experts, who perceive a WSN as a (promised to be) easy to deploy black box. This work presents the deployment experience of a WSN, as conducted by domain experts, in a ground improvement area. Building upon off-the-shelf solutions, a fuel cell powered gateway and 21 sensor devices measuring acceleration, inclination, temperature and barometric pressure were installed to monitor ground subsidence. We report about how poor GSM service, malfunctioning hardware, unknown communication patterns and obscure proprietary software required in-field ad-hoc solutions. Through the lessons learned, we look forward to investigating how to make the deployment of these systems an easier task. sensor network deployment; experiences; in-field debugging http://www.mdpi.com/2224-2708/2/1/156 Online en 2224-2708 10.3390/jsan2010156 1 TomásFernández-Steeger MatteoCeriotti Jó AgilaBitsch Link MatthiasMay KlausHentschel KlausWehrle inproceedings 2012-hummen-cloud 2012 12 3 232-240 sensorcloud fileadmin/papers/2012/2012-hummen-cloud.pdf IEEE Proceedings of the 2012 IEEE 4th International Conference on Cloud Computing Technology and Science (CloudCom), Taipei, Taiwan Taipei, Taiwan Fourth IEEE International Conference on Cloud Computing Technology and Science en 978-1-4673-4511-8 10.1109/CloudCom.2012.6427523 1 RenéHummen MartinHenze DanielCatrein KlausWehrle techreport 2012-weingaertner-fgsn-sim-iot 2012 9 26 SEEMOO-TR-2012-0 11.

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.

In Onion Routing a static tunnel through an overlay network is build via layered encryption. All traffic exchanged by its end points is relayed through this tunnel.In contrast, this paper introduces dynamic multipath Onion Routing to extend the static Onion Routing paradigm. This approach allows each packet exchanged between two end points to travel along a different path. To provide anonymity the first half of this path is selected by the sender and the second half by the receiver of the packet. The results are manifold: First, dynamic multipath Onion Routing increases the resilience against threats, especially pattern and timing based analysis attacks. Second, the dynamic paths reduce the impact of misbehaving and overloaded relays. Finally, inspired by Internet routing, the forwarding nodes do not need to maintain any state about ongoing flows and so reduce the complexity of the router. In this paper, we describe the design of our dynamic Multipath Onion Router (MORE) for peer-to-peer overlay networks, and evaluate its performance. Furthermore, we integrate address virtualization to abstract from Internet addresses and provide transparent support for IP applications. Thus, no application-level gateways, proxies or modifications of applications are required to sanitize protocols from network level information. Acting as an IP-datagram service, our scheme provides a substrate for anonymous communication to a wide range of applications using TCP and UDP.

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.
