无线传感器网络中基于能量效率的多路径路由算法
An Energy-Efficient Multipath Routing Scheme for Wireless Sensor Networks
摘要
Abstract
The energy supply of nodes will be limited strictly in wireless sensor networks (WSNs). Considering the characteristics, a new scheme called energy-efficient multipath routing (EMR) is presented. Based on AODV,this scheme analyses path hopcount, residual energy of nodes and energy status of sensor networks. The packets can be transmitted along the multiple paths according to the minimum hop or their Key Energy Ratio, reduces the network energy consumption, and avoids heavy traffic on some critical nodes. The simulation results show that compared with AODV the scheme effectively improves the packet delivery ratio, and the end-to-end delay,delays the emergence of the death node, and prolongs the network lifetime.关键词
