Abstract

Applying wireless sensor network to emergency management is helpful to predict latent disaster and prevent or lessen the harm. In some cases of emergency management, it is not necessary to monitor the entire area all the time, and only need to employ a few of mobile sensors to monitor a number of Points of Interest (POIs) periodically. Due to the cost restriction, the number of mobile sensors is limited. Moreover, there may be some obstacles in the monitoring field, which makes mobile sensor cannot reach some POIs directly. In this paper, we address the Minimum-Delay POIs Coverage problem in Emergency Management, which is how to schedule the limited number of mobile sensors to monitor the POIs in a region with obstacles such that the POIs coverage delay is minimized. Firstly, we calculate the shortest distance between any two POIs in the monitoring field with obstacles to construct a weight complete graph. Secondly, we propose an algorithm named Obstacle − TSP − S to address the minimum-delay POIs coverage problem. By the comprehensive simulations, we evaluate the performance of the proposed algorithm. The simulation results show the efficiency of our algorithm.
