Duoqiang Wang, Qi Qin, Jiying Yu · 2012
This paper analyzes the existing algorithms of coverage of WSN, then proposes an algorithm of coverage of network base on the probability sensing model. First, the algorithm judges whether exists a sponsor set of the node i where node i is any node in the monitoring area. If the sponsor set is not existed, the node must keep working; else the algorithm executes the next steps. Determine whether the node would go to sleep taking into the probability of networks. The simulation results show that the agreement reduces the number of working nodes, extends the network's life cycle effectively, and achieve the desired network coverage.
