Abstract

Detecting a moving object inside an irregular region is one of the most fundamental challenges of Wireless Sensor Networks. The performance of an effective and efficient sensor network for detecting moving object is highly related to the proper deployment of the sensors. In this paper we have addressed the problem of deploying heterogeneous sensors in a regular space with a grid-based routing model which may further be extended to an irregular one. We have also considered clustered energy model to detect and replace of a dead node if exist in the network. The simulation shows that with the increase number of deploying nodes for larger space, this model has more than 50% gain with guaranteed shortest path than that of the existing broadcast techniques. More over, the worst case of this deployment algorithm is compare to the average case with existing one.
