摘　　要：针对水声传感器网络长时延和高能耗的问题,提出了基于距离门限的自适应路由协议ARBDT(AdaptiveRouting Protocol Based on Distance Threshold)。该协议采用单路径逐跳信息传输方式,节省了路由开销;同时根据网络密集程度自适应地调整距离门限,抑制了冗余节点的回应,降低了控制包冲突的概率,使发送节点能快速获取转发节点。仿真结果表明,与SBR(Sector-Based Routing)协议相比,ARBDT协议能缩短时延,降低网络能耗,从而获得更好的性能。Aimed at the problems of long propagation delay and high energy consumption in underwater acoustic sensor networks,an ARBDT （ Adaptive Routing Protocol Based on Distance Threshold） is presented. It decreases routing overheads by delivering data packets hop by hop in single path. In addition,ARBDT can adaptively adjust distance threshold according to network density,which restrains unnecessary responses from redundent nodes to reduce the collision probability of control packets,and makes the sender select next forwarder rapdily. Compared with the SBR （ Sector-Based Routing） protocol,simulation tests show that the proposed protocol can achieve better performance on delay and energy consumption.
