摘　　要：水声通信网在军事、能源、自然灾害预防和处理等方面均具有巨大的应用潜力。针对当前水声通信网按需路由算法存在网络开销大、能量不均衡的问题,提出了旨在改善网络整体性能的HTREB算法。通过采用洪泛抑制与优先使用剩余能量均方差较大的节点进行路由查找,来减少控制分组的转发,并均衡节点能量。基于Opnet软件进行了仿真。结果表明,与现有按需路由算法相比,HTREB算法降低了网络开销8.08%~29.32%、端到端平均能耗4.70%~19.86%、平均端到端延时30.58%~71.63%,延长了网络生存期29.61%以上。因此,HTREB算法明显改善了系统的整体性能。UACN have great application potential in military,energy source,prevention and treatment of natural disasters.The current on-demand routing algorithms have some problems such as high network overhead and unbalanced energy consumption.To solve these problems,HTREB algorithm is suggested to improve the total performance of the networks.Based on the flooding suppression,nodes with more residual energy is preferred to find the routing,and then to reduce forwarding of controlled packets and to balance the energy consumption between nodes.The algorithm is simulated based on the software Opnet.Results show that 8.08% ~ 29.32% of network overhead,4.70% ~ 19.86% of average end-to-end energy consumption,30.58% ~ 71.63% of the average end-to-end delay are reduced,compared to the current on-demand routing algorithms.Furthermore,the network lifetime is prolonged by at least 29.61%.Therefore,the total performance of the system is evidently improved through our algorithm.
