Abstract:
|
Detecting and localizing a target and estimating its signal are fundamental tasks in wireless sensor networks. Performing them efficiently while conserving energy and communications costs often requires distributed processing. We propose an algorithm for local neighborhood voting and show that performing these operations before global data fusion can significantly improve target detection and reduce communications costs compared to standard global methods. We also show that the same algorithm can improve target localization, where methods based on collecting signal data from a small subset of sensors determined by local operations can achieve performance levels similar to methods based on the full data, but at a fraction of the communications cost.
