摘　　要：针对三维水下传感器网络模型,对水下传感器网络的覆盖优化问题进行了描述,提出利用虚拟势场算法CAT(coverage-enhancing algorithm for three-dimensional sensor networks)调整水下传感器节点与浮标节点间缆绳的距离,逐渐消除网络中的感知重叠区域和覆盖盲区,进而实现整个水下传感器网络覆盖增强。在仿真实验中,通过CAT算法与ETG算法的比较,验证了CAT算法的有效性。According to the model of underwater sensor network in three dimension,we formally describe the optimization problem of coverage for underwater sensor networks.Then we propose a scheme,which bases on the virtual potential field algorithm CAT to adjust the rope distance between the nodes of the underwater sensor network and the float node.It eliminates the sensing overlapped area and coverage fade zone,which herein enhances the coverage of the entire underwater sensor network.Simulation results validate the efficiency of CAT （coverage-enhancing algorithm for three-dimensional sensor networks） algorithm by comparing with the ETG algorithm.
