摘　　要：针对水下传感器网络能量消耗大、延迟时间长、信道利用率低等问题,提出了一种带选择适应性的水下传感器网络分布式路由算法(AS-UWSN)。AS-UWSN使数据包成为一种具有以最大阈值为能耗界限的选择性和具有以最大信息素浓度为搜索对象的适应性的蚁群,以当前链路的能量损耗、网络延迟、误包率作为信息素的产生因子,每次迭代时蚁群都会直接搜索最优的节点转发路径,迭代次数少且具有更好的实时性和灵活性。实验仿真结果表明,在水下无线传感器网络的能量优化以及延迟时间控制、信道利用率提升上采用AS-UWSN算法得到了较好的效果。Taking into account the problem of the underwater sensor network,such as big energy consumption,long delay time,low channel utilization,this paper proposed an underwater sensor network distributed routing algorithm（ AS-UWSN）with selective and suitability. AS-UWSN algorithm made data packet to be a selective and adaptive ant colony that had maximum threshold as energy limits and had greatest concentration of pheromone as search object. The algorithm used the energy loss,network delay,packet error rate as an pheromone production factor in the current link,ant would directly search the optimal node forwarding path in each iteration,no only had fewer iteration times but aslo had better real-time performance and flexibility. Simulation results show that the effect of energy optimization and delay time controlled,channel efficiency improved is better by using AS-UWSN algorithm in underwater wireless sensor networks.
