异构有向传感器网络两阶段动态覆盖算法
Two-stage Dynamic Coverage Algorithm for Heterogeneous Directional Sensor Network
摘要
Abstract
In order to solve the problems of redundant coverage and higher energy consumption in the deployment of the heterogeneous directional sensor network,this paper proposes a two-stage dynamic coverage algorithm based on hybrid movement strategy.The proposed algorithm uses stepwise method to adjust the perception direction of the nodes,so as to reduce coverage redundancy.In this basis,it detects the coverage holes and uses the improved differential algorithm to move the redundant nodes into optimized location,so as to repair the coverage holes.Experimental results show that the proposed algorithm can improve the network coverage rate and reduce the energy consumption effectively.关键词
