摘要
针对当前无线传感器网络路由协议存在丢包率高、能耗大等缺陷,提出一种基于能量感知的无线传感器路由协议。在建立数据转发路由的过程中,引入节点能量感知机制,选择剩余能量较大的节点作为下一跳节点,防止剩余能量较小的节点参与路由构建;在节点工作的过程中,引入周期、异步工作/休眠机制节约节点的能量开销。采用仿真对比实验对路由协议的性能进行测试,实验结果表明,该协议减少了网络数据转发的丢包率,提高了器节点的能耗。
The current outing protocols of wireless sensor network have defects including high packet loss rate and large energy consumption etc.,a routing protocol of wireless sensor based on energy aware was proposed to solve the problem.In the establishment of data forwarding routing process,the node energy aware mechanism was introduced to choose the larger residual energy node as the next hop routing nodes and to prevent the node with smaller residual energy from participating in route construction.In the nodes working process,the cycle,asynchronous work/sleep mechanism was introduced to save the node energy cost,and the performance of routing protocol was tested by comparison experiments.The experimental results show that,the proposed routing protocol can improve nodes energy rate of wireless sensor network and reduce packet loss rate.
