摘　　要：针对水下传感器网络,结合水声通信和光通信两种通信方式的优点,设计了新的水下传感器网络结构。根据水下目标分布的先验概率模型,提出了混合水下传感器网络部署算法,实现了水下数据的高速传输和水下目标区域的高效覆盖。仿真结果表明,算法能够较好地减少网络部署的节点数目、缩短数据传输延时,减少能量损耗,延长网络寿命。For underwater sensor networks, combined with the advantages of underwater acoustic communication and optical communication, we designed a new structure of underwater senor networks. Based on prior probability model of underwater targets distribution, a hybrid underwater sensor network deployment algorithm （HNDA） is proposed to achieve efficient high-speed transmis- sion of underwater data and coverage of underwater target area. Simulation results showed that HNDA can reduce the number of nodes of network and the data transmission delay, reduce energy consumption and prolong the life of the network aspects.
