摘　　要：针对水声传感器网通信带宽低、节点能耗高的特点,提出一种基于网络编码的多径路由协议。该协议在路由过程中通过在主链路和后备链路之间动态切换创造更多的网络编码机会进行数据传输,从而优化网络带宽利用率,并降低冗余数据包重传造成的能量消耗。仿真结果表明:基于网络编码的多径路由协议可以在提高水声传感网吞吐量的同时,有效降低网络能量消耗。Considering the characteristics of low communication bandwidth and high energy consumption of nodes in underwater acoustic sensor networks（UWASNs）,a multi-path routing protocol based on network coding（MRNC） is presented.MRNC creates more network coding opportunities for data transmission through dynamic switching over main links and backup links during the process of routing,which in turn optimizes the network bandwidth utilization rate,and reduces the energy consumption caused by retransmission of redundant packets.Simulation results demonstrate that MRNC can improve the network throughput as well as reduce energy consumption in UWASNs.
