摘　　要：根据传统的无线传感器PEGASIS算法提出一种针对水声通信领域的改进型PEGASIS算法,改进型PEGASIS算法通过比较节点与簇头和服务器的传播损失,改变了单个节点的信息传播方向和融合过程,经建模仿真,此算法相较于LEACH和典型PEGASIS算法可以进一步降低整个网络的功耗,并在某些链路上减少网络运行周期,提高了网络的使用效率,对于水声通信组网有较大的借鉴作用。This paper proposes an improved PEGASIS algorithm for the field of underwater acoustic communication based on the traditional wireless sensor PEGASIS algorithm. The improved PEGASIS algorithm changes the information propagation direction and fusion process of a single node by comparing the propagation loss of the node with the cluster head and the server. After modeling and simulation, compared with LEACH and typical PEGASIS algorithms, this algorithm can further reduce the power consumption of the entire network, and reduce the network operation cycle on some links, and improve the efficiency of the network. There is a great reference effect to underwater acoustic communication network.
