摘要

无线传感器网络中节点大多采用电池供电，让节点以低能耗将采集的数据传递到信宿，对无线传感器网络有效运行极为重要.该文提出了能量有效的可靠机会路由EROR（Energy-efficient Reliable Opportunistic Routing），它利用结合节点剩余能量和链路上收发双方的总能耗的转发代价，选择转发节点集合（简称“转发集”）、主转发节点和协助转发节点，让节点调节发射功率并利用随机线性编码把数据包分片编码发送到转发集，进而以多跳方式把数据可靠低能耗地传递到信宿.仿真结果表明：在网络生存时间和能耗方面，EROR比已有路由策略CodePower更优.

Abstract

The nodes in Wireless Sensor Networks(WSNs)are usually powered by battery.It is extremely important to let the nodes deliver data to the destination in an energy-efficient manner such that the WSNs have longer runtime.In this paper

the Energy-efficient Reliable Opportunistic Routing(EROR)is presented.The EROR uses the forwarding cost

which takes into account node's residual energy and the total energy consumption expended by the nodes over a wireless link;chooses the forwarding set consisting of forwarding nodes(FNs)

the main FN

and the assistant FNs;and allows a node to change its transmission power to transmit the encoded packets

which are generated by randomly linear network coding

to the forwarding set such that the data are delivered to the destination in a multi-hop

reliable

and energy-efficient way.Simulation results indicate that the EROR outperforms the existing CodePower routing in terms of network lifetime and energy consumption.
