摘　　要：在水下无线传感网(underwater wireless sensor networks,UWSNs)中,通过融合水下声通信和网络拓扑特性可设计高性能的路由协议,提高UWSNs数据传输性能。为此,提出基于能量效率的簇路由协议,记为EECR(energyefficient cluster routing)协议。为最小化能量消耗,平衡节点负担,使每个节点被选为簇头的概率相同,提高簇结构的稳定性;引入剩余能量因子和距离因子修正LEACH的阈值函数,降低簇头能量消耗。仿真结果表明,所提EECR协议有效地提高了数据包传递率,降低了节点能量消耗。In underwater wireless sensor networks（UWSNs）,one way to improve the data collection in UWSNs is through the design of routing protocols considering the unique characteristics of the underwater acoustic communication and network topology.Therefore,energy-efficient cluster routing for underwater wireless sensor networks was proposed,which was marked as EECR.To minimize the energy consumption,loads among all the nodes were distributed equally.The energy consumption of each node was equally utilized as each node with equal probability was selected as a cluster head（CH）.Residual energy factor and distance factor were introduced to correct threshold function for LEACH protocol,which reduced the energy consumption of cluster head.Simulation results show that EECR protocol has good performance in terms of energy consumption and packet delivery ratio.
