针对周期性数据收集无线传感器网络应用,提出一个能量收集无线传感网络路由协议EHRP,以高效的能量估计和链路评估为基础,通过基于收集能量优先的选路实现多跳报文转发,构建起能量均衡消耗的多跳传感器网络.仿真结果表明在具有能量收集能力的传感器网络中,EHRP能够充分利用节点的能量收集能力,实现网络能量均衡,延长网络的生命周期,同时提高了数据传榆的可靠性.
This paper presents an energy balanced routing protocol for many-to-one data collection in wireless sensor networks, called EHRP. The novelty of EHRP includes: The energy harvesting is put in the preferred position to reduce the energy consumption, and the periodical link quality estimation is used to provide reliable routing in sensor networks. The simulation results indicate that EHRP can greatly prolong the network lifetime and improve muting data transmission reliability in the networks with power harvesting.
