Artificial Potential Based WSN Coverage Enhanced Algorithm
Jia Wang · Chuangan jishu xuebao · 2012
Coverage is one of the most important performances of WSN.Sink ' s mobility can improve it.Artificial potential is suitable to illustrate the relationship between common nodes and mobile Sinks.A novel artificial potential based algorithm for Sinks moving to improve coverage is proposed.Data collected by nodes could be sent to Sinks by multi-hop.The force derived from the artificial potential makes the Sink move to equilibrium state in order to achieve higher coverage after the random nodes deployment at first.It ' s not necessary to know the environment of whole WSN before band,so the method can be done in real-time.The specific steps of this algorithm are given.Finally,the effectiveness of this method is illustrated by a simulation.
