无线传感器网络跨层能耗均衡路由协议

Cross-Layer Energy Balanced Routing Protocol in Wireless Sensor Networks

在改进最小代价路由协议的基础上,建立一个跨层能量管理模型,将网络各层的能耗、流量、非均匀特性等融合到路由建立、路由选择和路由维护中,设计了节点路由选择与基站全局调节相结合的双层规划的跨层能耗均衡路由协议(CEBR)。该协议能综合优化各层能量消耗,支持多路径流量均衡分配,以节省能量、均衡网络能耗来延长网络的稳态生命周期。仿真实验结果表明:CEBR与MCF协议相比较,在能耗均衡和延长网络稳态寿命上更优。

Based on improving minimum cost forwarding routing protocol,a new cross-layer energy balanced routing protocol（ CEBR） was designed for wireless sensor networks. CEBR protocol used a model of cross-layer energy management and a two-tier approach combined route selection of node and global regulation of base station. In order to prolong the lifetime of a sensor network,the proposed routing protocol optimized energy consumption at each layer,and integrated energy consumption information,data flow,non-uniform features of each layer into the process of route establishment,route selection and route maintenance,which optimized the control of network energy consumption and used multiple paths to support flow balance. The simulation results show that the improved CEBR routing protocols are better than MCF routing protocols in balancing energy consumption and prolonging network lifetime.
