A Holistic Solution to Pursuer-Evader Tracking in Sensor Networks

Free registration required

Executive Summary

In this paper, the authors devise a holistic solution to the pursuer-evader tracking problem taking into account the limitations of the Wireless Sensor Networks (WSNs) as well as the dynamics of both the pursuer and evader. More specifically, they present an optimal strategy for the pursuer to capture the evader despite the delayed and imprecise information available at the pursuer-side. In order to minimize the communication overhead while ensuring capture, they provide an optimal evader-sampling scheme that adjusts the sampling frequency based on the strategies of the pursuer and evader, as well as the distance between the pursuer and evader.
