Abstract
Wireless sensor networks offer the potential to significantly improve the performance of pursuers in
pursuit-evasion games. In this paper, we study several sensor network systems, their interaction
with the pursuers, and the effect on pursuer performance. We propose a general framework to solve
the pursuit-evasion problem and present new centralized as well as distributed methods.
Specifically, we address three issues in the design of pursuers based on data provided by the
sensor network : a) how to identify evader moving patterns, (b) how to predict the evader locations
using different evader moving models, and c) how to choose the most efficient pursuit strategies.
We propose efficient algorithms to solve these problems and show that they are effective in
reducing the capturing time in our simulations. We also compare the distributed and centralized
methods. Experimental results show that the distributed method is efficient and produces solutions
close to the centralized method.
