面向客运车站环境监测的WSN覆盖策略
Coverage strategy of WSN for environmental monitoring of passenger station
摘要
Abstract
It is of great significance for environmental monitoring of passenger station to ensure the safe operation and provide comfortable travel for passengers.This paper mainly studies,based on Wireless Sensor Network (WSN),coverage strategy for environmental monitoring of the passenger station.According to the deployed sensor nodes,the monitored area is divided by Voronoi diagram and the coverage status of all triangles in it is calculated.Then an algorithm named Voronoi Triangle Coverage Ratio (VTR) is presented,which can repair the coverage holes by adding corresponding new nodes.The simulation results show that the proposed algorithm not only achieves the full coverage,but also effectively reduces the redundant coverage due to mass deployed sensor nodes.关键词
