Unstable links, although often promising to be of large routing progress, are not considered for packet forwarding as link estimators typically cannot handle their dynamics. In this paper we introduce short-term link estimation to capture link dynamics at a high resolution in time and to identify when these render a link temporarily reliable or unreliable. We identify such dynamics based on packet overhearing, predict short-term availability and unavailability, and adapt neighbor tables, thereby enlarging the set of links useable by any routing algorithm. Additionally, we show that short-term link estimation integrates seamlessly into today's sensor network link estimators and routing protocols.}, tags = {wld}, url = {fileadmin/papers/2008/2008-becher-hotemnets-linkestimation.pdf}, misc2 = {Online}, publisher = {ACM Press}, address = {New York, NY, USA}, booktitle = {Proceedings of Fifth Workshop on Embedded Networked Sensors (Hot EmNets'08), Charlottesville, VA, USA}, event_place = {Chalottesville, USA}, event_name = {Fifth Workshop on Embedded Networked Sensors (Hot EmNets'08)}, event_date = {June 2-3, 2008}, language = {en}, ISBN = {978-1-60558-209-2}, reviewed = {1}, author = {Becher, Alexander and Landsiedel, Olaf and Kunz, Georg and Wehrle, Klaus} } @Inproceedings { 200804landsiedelIPSN08TimingMatters, title = {When Timing Matters: Enabling Time Accurate \& Scalable Simulation of Sensor Network Applications}, year = {2008}, pages = {344-354}, abstract = {The rising complexity of data processing algorithms in sensor networks combined with their severely limited computing power necessitates an in-depth understanding of their temporal behavior. However, today only cycle accurate emulation and test-beds provide a detailed and accurate insight into the temporal behavior of sensor networks. In this paper we introduce fine grained, automated instrumentation of simulation models with cycle counts derived from sensor nodes and application binaries to provide detailed timing information. The presented approach bridges the gap between scalable but abstracting simulation and cycle accurate emulation for sensor network evaluation. By mapping device-specific code with simulation models, we can derive the time and duration a certain code line takes to get executed on a sensor node. Hence, eliminating the need to use expensive instruction-level emulators with limited speed and restricted scalability. Furthermore, the proposed design is not bound to a specific hardware platform, a major advantage compared to existing emulators. Our evaluation shows that the proposed technique achieves a timing accuracy of 99\% compared to emulation while adding only a small overhead. Concluding, it combines essential properties like accuracy, speed and scalability on a single simulation platform.}, url = {fileadmin/papers/2008/2008-04-IPSN-2008-landsiedel-Timing-Matters.pdf}, misc2 = {Print}, publisher = {IEEE Computer Society}, address = {Washington, DC, USA}, booktitle = {Proceedings of the 7th ACM International Conference on Information Processing in Sensor Networks (IPSN 2008), St. Louis, MO, USA}, language = {en}, ISBN = {978-0-7695-3157-1}, reviewed = {1}, author = {Landsiedel, Olaf and Alizai, Muhammad Hamad and Wehrle, Klaus} }
