Wireless Sensor Network Random Distribution Model and Coverage Control Research

The deployment and coverage of nodes is a fundamental problem in wireless sensor network,in the environment of nodes′random and high-density deployment,the mathematical model and simulation experiment proved the node distribution with Poisson distribution characteristics and quantified the perception radius of deployed nodes,the distributed density and the area of coverage,the relationship of k-coverage,and the model of covered control.In the premise of ensuring the effective covering area of monitoring for node the numbers of dormancy nodes approximately were obtained,which provided a reference for the experiments of sensor node random distribution and researched about the nodes deployment and control reference problems.The simulation showed that the mathematic model can effectively achieve minimum nodes and maximize coverage area in network k-coverage.
