Title: Optimized Design/Configuration of Wireless Ad Hoc and Sensor Networks

 

Abstract:

Optimization of wireless network design/configuration has relied on discrete-event simulators that measure performance metrics. However, the design of future tactical networks prior to battlefield deployment faces significant challenges due to the diversity of algorithms/protocols that can be used and the variety of parameters/parameter settings. This talk is composed of two parts. In the first part, we show how to automatically select algorithms and parameter settings to optimize a desired objective and satisfy certain constraints. We propose a novel heuristic (Sequential Parameter Optimization or SEPO) for searching through the possible settings and selecting the design options. SEPO is very efficient in terms of both parameter optimization and convergence speed. In the second part of this talk, we discuss how to optimize the lifetime of a wireless sensor network by activating/deactivating sets of sensors in the field without compromising the quality of field coverage.
