摘　　要：分析了无线传感器网络传输信息位置相关性特点以及节点能耗模型,运用基于能量指标和距离指标的簇首选举方法,建立了一种基于节点剩余能量和传输距离的跨层自适应周期簇间路由性能模型。该模型均衡网络节点能耗和负载。簇间通信根据其下一跳簇节点的能量、能耗因子、RSSI以及能耗指数等进行选择。仿真结果表明,与已有的跨层设计和分簇协议相比,该模型有效地延长了网络寿命,提高了网络的吞吐量。该模型能效高,控制开销较低,能量负载均衡。The character of location-related transmission information and model of energy consumption were analyzed.A cross-layer adaptive round inter-clusters routing was proposed based on the cluster election method of the energy index and distance index.The model can balance traffic load and energy consumption of nodes.Communication of inter-clusters is based on energy and energy-consumption factor and RSSI and energy index of next hop.By comparison with otherclustering and cross-layer routing protocols,the simulation results show that the model prolongs the lifetime and improves the throughput.The model is high energy-efficiency,small control overhead and well balanced energy load.
