无线传感器网络中利用随机网络编码的低能耗可靠机会路由
Energy-Efficient Reliable Opportunistic Routing Applying Random Network Coding for Wireless Sensor Network
摘要
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 pa-per,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 trans-mission 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.关键词
