无线传感网中一种能量均衡的分簇路由算法
An Energy Balanced Clustering Routing Distributed Algorithm in Wireless Sensor Networks
摘要
Abstract
One of the most challenging and critical problem in Wireless Sensor Networks ( WSNs) is to reduce energy consumption to prolong network life. In this paper,propose an energy balanced clustering routing distributed algorithm. The algorithm comprises of three phases,namely cluster head selection,cluster setup and data routing. The CHs are selected in distributed manner based on residual energy and the neighbor cardinality. In the setup phase,each non-CH sensor node joins a CH within its communication range based on the cost value of the CHs. In data routing phase,CRA-EB first uses single hop communication within each cluster and then performs multi-hop communication between the clusters. For inter-cluster routing,a CH measures the cost of each path from itself towards base station while selecting other CH as a relay node for data forwarding on those paths. The simulation results show that,compared with the LEACH and DEBR algorithm,the CRA-EB algorithm is more effective in terms of energy consumption and the number of live sensor nodes.关键词
