Study on Worst Case Coverage of Mobile Sensors in Hybrid Wireless Sensor Networks

Abstract:

Coverage has recently emerged as a premier research topic. This paper addresses the problem of monitoring of targets with hybrid network, which is composed of some static sensors randomly deployed in the sensing area and some mobile sensors deployed in the edge. Probability model is used to find all the maximal breach paths. The nearest mobile nodes to the maximal breach paths will move to the maximal breach path with certain speed, to ensure that the target can be detected within the monitoring area. Algorithm is presented for using mobile nodes to enhance barrier coverage. Simulation confirms the efficiency of our moving strategy.
