摘要: 在无线传感器网络(WSN)按需距离矢量(AODV)路由协议的基础上,提出一种基于能量感知的WSN按需多径路由协议——AODV-EALB。综合考虑链路质量、转发优先级系数、剩余能量和节点接收数据包的信号强度,均衡网络节点能耗。仿真实验结果表明,AODV-EALB协议能降低丢包率,延长网络生存周期。

Abstract: On the basis of Wireless Sensor Network(WSN) Ad Hoc On-demand Distance Vector(AODV) routing protocol, this paper proposes a WSN on-demand multipath routing protocol based on energy-aware, named AODV-EALB. It combines with energy link quality and forwarding priority factor. Through the consideration of the surplus energy and signal strength of node acceptging packets, it balances the network node energy consumption. Simulation experimental results show that AODV-EALB protocol can reduce the packet loss rate and extend the network lifetime.

Key words: Wireless Sensor Network(WSN), Ad Hoc On-demand Distance Vector(AODV) routing protocol, energy-aware, link quality
