摘　　要：针对基于压力的水下无线传感器网络路由协议数据包传输路径距离过长、能量消耗不均衡等问题,提出一种基于REPBR跳数效用转发的改进路由算法。采用一种效用函数策略即加入剩余能量、节点间的跳数和链路质量3种因子解决能量消耗不均衡的问题,引入最小跳数算法获取节点到sink节点的跳数值,在数据包转发阶段综合比较路由效益选择最佳转发节点。仿真结果表明,改进后算法相比REPBR、EEDBR、DBR有较小的网络时延,提升了数据包的转发效率,提高了网络性能。The data packet transmission path of the pressure-based underwater wireless sensor network routing protocol is too long and the energy consumption is unbalanced,to solve the problems,an improved routing algorithm based on REPBR hop number utility forwarding was proposed.An utility function strategy was adopted to solve the problem of unbalanced energy consumption by adding three factors of residual energy,number of hops between nodes and link quality,and the minimum hop number algorithm was introduced to obtain the hop value from the node to the sink node,and the best forwarding node was selected by comprehensively comparing the routing benefits in the data packet forwarding stage.The simulation results show that compared with REPBR,EEDBR and DBR,the improved algorithm can better reduce the network delay,improve the forwarding efficiency of data packets and the network performance.
