摘　　要：为解决认知无线电网络有限的能量资源对全网路由的影响,提出了一种网络节点能量感知的路由算法EARP(Energy Aware Routing Protocol)。该算法允许根据单个节点的能耗和全路径从不同传输路径的相邻节点中选择路由。文章设计了路由维护策略,以防止链路传输过程由于能量耗尽引起路径中断。在相同的实验环境下,通过与LEACH路由协议进行仿真实验。结果表明,提出的EARP可以明显地平衡负载,保护低能量节点,延长网络生存时间,降低数据传输的丢包率和包延迟,可以提高传感节点的能耗,提供路由能力。In order to solve the impact of the limited energy resources of cognitive radio network on the whole network routing,an energy aware routing protocol(EARP)is proposed.The protocol allows routing based on simultaneous interpreting of the energy consumption and full path of a single node from adjacent nodes of different transmission paths.The article proposes a route maintenance strategy to prevent path interruption caused by energy depletion in the link transmission process.In the same experimental environment,the simulation experiment is carried out with LEACH Routing Protocol.The results show that the proposed Earp can significantly balance the load,protect low-energy nodes,prolong the network lifetime,reduce the packet loss rate and packet delay of data transmission,improve the energy consumption of sensor nodes and provide routing capability.
