Abstract

In this paper, we propose a distributed scheme to recognize the shape of a dynamic event region in wireless sensor networks; i.e., a scheme to track the shape of a part of a given field concerned with a dynamic event such as gas leakage and a fire. The basic idea of our proposed scheme is to identify several critical points in a given event region, and to periodically check the criticalness of such points. The performance of the scheme is experimentally evaluated by simulation. The result of simulations indicates that the proposed event tracking scheme correctly recognizes the move of an event region with sufficiently small number of transmitted messages compared with a centralized tracking scheme.
