摘　　要：基于水压路由广泛用于水下无线传感网络(Underwater Wireless Sensor Networks,UWSNs),这些协议利用传感节点的水压,并以贪婪多跳方式将数据传输至水面上的信宿。然而,贪婪转发存在路由空洞问题。为此,提出基于水压的抑制路由空洞的路由算法(Hydraulic Pressure based routing algorithm with suppressing routing-void,HPSRV)。HPSRV算法利用水压构建节点转发集,并计算转发权值,再设置定时器,进而产生下一跳转发节点。同时,利用边界转发策略解决处理路由空洞,通过计算节点的边界度量值,产生边界转发节点,进而降低边界转发跳数。实验数据表明,提出的HPSRV路由有效地提高了数据包传递率,且降低了端到端的传输时延,与VAPR协议相比,数据包传递率提高了约43%、端到端传输时延降低了约68%。Hydraulic Pressure based routing are widely used in Underwater Wireless Sensor Networks. Pressure level of sensor nodes is used to route data packet in greedy multi hop fashion to sinks deployed on the surface. However,greedy forwarding tends to result in routing-void problem. Therefore,Hydraulic Pressure based routing with suppressing routing-void（ HPSRV） is proposed in this paper. HPSRV protocol construct the forwarding set by pressure level of sensor nodes,and compute the forwarding weight,then set the timer in order to select the next-hop forwarding node. In addition,the routing-void problem is deal with by boundary forward strategy. Boundary forwarding node is selected by the boundary metric. The goal of it is to reduce the number of hops. Simulation data results that HPSRV protocol has a good performance in terms of average endto-end delay and packet delivery ratio. Compared with VAPR,packet delivery ratio of the HPSRV protocol is improved by about 43%,and average end-to-end delay is reduced by about 68%.
