摘　　要：从水环境监测的应用需求出发,提出了水下空间节点三维部署的目标和约束条件。同时,为了解决在三层水下无线传感器网络结构模型下,节点稀疏部署后,网络存在的能耗不均衡问题,提出一种非均匀简单立方格节点部署算法。该算法结合节点水声通信能耗模型,通过增加各层节点数目和调整节点间通信距离来控制节点能耗。从网络的生存时间和网络的能量消耗两方面对算法进行了分析和仿真,结果表明:本算法可以在保证网络覆盖要求的前提下,控制节点部署的密度,均衡节点的能量消耗,延长网络寿命。Starting from the requirements of water environment monitoring application,propose target and constraints of node deployment in 3D underwater space. And then,in order to solve imbalance energy consumption problems of nodes after sparse deployed in model of three-layer underwater wirless sensor networks（ UWSNs）,an inhomogeneous simple cubic lattice node deployment algorithm is proposed. This algorithm is designed by increasing the number of nodes of each layer and adjusting communication distance between nodes to control energy consumption of nodes combining energy consumption of underwater acoustic communication. The analysis and simulation on this algorithm from network lifetime and energy consumption is discussed,results show that the algorithm can not only guarantee the coverage requirements and control the density of nodes deployment,but also balance energy consumption of nodes and prolong the network lifetime.
