摘　　要：现阶段的水下传感器网络(UWSN,underwater sensor networks)路由算法的研究工作大多都没有对部署的水下环境做具体分析,不同水下环境与网络性能之间的相关性研究较少,同时针对水下信道利用率低、能量消耗和延迟时间较大等问题,提出融合了环境元素的水下传感器网络分布式路由算法(EE-UDRA),分析了不同的水下传播环境以及环境元素对路由算法性能的影响,通过增长型分组队列的管理方法重点解决了水下信道利用率较低的问题,并在提高信道利用率的基础上通过分析能耗或延迟的可控因素来寻找能耗最低或延迟最小的路由路径。实验结果显示,环境元素对相同算法的运行结果带来了一定的影响。在提高信道利用率的同时,EE-UDRA算法选择的最佳路由路径在减少能量消耗,缩短延迟时间上具有较好的效果。Most of present researches on the underwater sensor network routing algorithm have not made a specific analysis on the deployment of underwater environment,and there are few correlational studies between the different underwater environment and network performance.Meanwhile,taking into account some problems such as the low utilization of underwater channel,the fast consumption of energy and longer delay time,the distributed routing algorithm for underwater sensor networks combining enihvironmental factors has been proposed,and it analyzed the influence of the different underwater propagation environment and environmental factors on the performance of the routing algorithm. The problem of low utilization for the underwater channel was resolved through growing packet queue management methods.And on the basis of the improvement of the channel utilization,the lowest energy consumption or minimum delay routing path was searched by analyzing the controllable factors of energy consumption and delay.The experimental results indicated that the environmental factors have a certain impact on the running results with the same algorithm.The optimal routing path selected by this algorithm not only improved the information channel utilization,but also reduced energy consumption and the delay time with good results.
