Their main objective is to solve the scalability issue of ad-hoc networks by grouping nodes into clusters. The challenge in MANETs for those clustering algorithms is to cope with the high node mobility which affects the stability of the cluster structures. Wireless mesh networks consist of a static backbone and a number of mobile nodes. In the backbone of a wireless mesh network the topology is relatively static. However, topology changes occur due to frequent link losses and temporary link instability. Due to the static nature of the backbone, mobility-based approaches are not suitable in this case. In this paper, we state the important aspects for stable clustering in wireless mesh networks with unidirectional links based on the investigation of a 45-node wireless mesh testbed. We analyze well-known clustering algorithms and their performance in a large-scale testbed. Finally, we propose a new clustering algorithm called Stable Link Clustering Algorithm (SLCA). fileadmin/papers/2010/2010-lora-clustering-MESH.pdf http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=5683417 Print IEEE Proceedings of the IEEE Global Telecommunications Conference GLOBECOM 2010, Miami, USA Miami, FL, USA IEEE Global Telecommunications Conference, GLOBECOM 2010 6 - 10 December 2010 en 978-1-4244-5636-9 10.1109/GLOCOM.2010.5683417 1 MartinKrebs AndréStein Mónica AlejandraLora Girón inproceedings 2010-sensys-sasnauskas-coojakleenet 2010 11 383--384 High-coverage testing of sensornet applications is vital for pre-deployment bug cleansing, but has previously been difficult due to the limited set of available tools. We integrate the KleeNet symbolic execution engine with the COOJA network simulator to allow for straight-forward and intuitive high-coverage testing initiated from a simulation environment. A tight coupling of simulation and testing helps detect, narrow down, and fix complex interaction bugs in an early development phase. We demonstrate the seamless transition between COOJA simulation and KleeNet symbolic execution. Our framework enables future research in how high-coverage testing tools could be used in cooperation with simulation tools. kleenet fileadmin/papers/2010/2010-osterlind_sasnauskas-sensys-coojakleenet.pdf Print ACM

The high level of modeling detail (hardware elements are partially modeled in a cycle-accurate fashion) is required for many core design tasks. At the same time, the high computational complexity of virtual platforms caused by the detailed level of simulation hinders their application for modeling large networks of embedded systems. In this paper, we propose the integration of virtual platforms with network simulations, combining the accuracy of virtual platforms with the versatility and scalability of network simulation tools. Forming such a hybrid toolchain facilitates the detailed analysis of embedded network systems and related important design aspects, such as resource effectiveness, prior to their actual deployment. https://www.comsys.rwth-aachen.de/fileadmin/papers/2010/2010-schuermans-weingaertner-network_centric.pdf Online IEEE Proceedings of the IEEE International Conference on Communications (ICC), Cape Town, South Africa, May 23-27 en 978-1-4244-6402-9 1550-3607 10.1109/ICC.2010.5502185 1 StefanSchürmanns EliasWeingaertner TorstenKempf GerdAscheid KlausWehrle RainerLeupers inproceedings 2010-ipsn-sasnauskas-kleenet 2010 4 12 186--196 Complex interactions and the distributed nature of wireless sensor networks make automated testing and debugging before deployment a necessity. A main challenge is to detect bugs that occur due to non-deterministic events, such as node reboots or packet duplicates. Often, these events have the potential to drive a sensor network and its applications into corner-case situations, exhibiting bugs that are hard to detect using existing testing and debugging techniques. In this paper, we present KleeNet, a debugging environment that effectively discovers such bugs before deployment. KleeNet executes unmodified sensor network applications on symbolic input and automatically injects non-deterministic failures. As a result, KleeNet generates distributed execution paths at high-coverage, including low-probability corner-case situations. As a case study, we integrated KleeNet into the Contiki OS and show its effectiveness by detecting four insidious bugs in the uIP TCP/IP protocol stack. One of these bugs is critical and lead to refusal of further connections. automated protocol testing, experimentation, failure detection, wireless sensor networks kleenet fileadmin/papers/2010/2010-04-ipsn-sasnauskas-KleeNet.pdf Print ACM

It assigns virtual coordinates to nodes based on the statistical distribution of their distance from a small set of beacons. The distance metric predicts the current location of a node in its address distribution. Our initial results from a prototype implementation over real testbeds demonstrate the feasibility of SVR. wld https://www.comsys.rwth-aachen.de/fileadmin/papers/2010/2010-alizai-ipsn-pad.pdf http://portal.acm.org/citation.cfm?id=1791257 Print ACM

To further increase flexibility, we believe cross-layer architectures should adapt themselves to these changing conditions, just as they adapt the network stack, devices, and applications. In this paper, we propose CRAWLER, a novel cross-layer architecture that combines three core properties: signaling between all layers and system components; extensibility and adaptability at runtime; and high usability for cross-layer developers. CRAWLER increases flexibility, as well as expediting and simplifying cross- layer development.

The novelty of the proposed method is the incorporation of both, speech bits as well as protocol header bits, into the ISCD process. The header bits take the role of pilot bits having perfect reliability. These bits are distributed over the frame as strong supporting points for the MAP decoder which results in a significant enhancement of the output speech quality compared to the benchmark scheme using ISCD for speech only. For this approach, we exploit new cross-layer concepts that support the direct communication between non-adjacent layers. These concepts enable the iterative exchange of extrinsic information between the source decoder located on the application layer and the channel decoder located on the physical layer. This technique can also be applied to audio and video transmission. refector fileadmin/papers/2010/2010-01-scc-breddermann-iscd.pdf CD-ROM / DVD-ROM Rudolf Mathar, Christoph Ruland VDE Verlag
