According to the distances from underwater nodes to the base station,the depth of nodes as well as nodes energy,a new cluster head selection algorithm is proposed and the optimum ratio of the three factors is verified. Then the routing node selection process based on nodes' communication distance is introduced, based on which a routing protocol based on clustering is explored so as to solve the high energy consumption and delayed problems of underwaer sound channel. Through comparing with the existing routing strategies DBR and DBMR by experiments, results show that the proposed routing protocol has lower energy consumption, which is more suitable for underwater nodes communication.%根据水下节点到水面基站的距离、节点到水表面的深度、节点的剩余能量,提出一种簇头节点选择算法,探讨3种因素在选择簇头时的最佳权重,并引入基于节点通信距离的路由节点选择过程,据此提出基于分簇思想的路由协议,以解决水下声道高能耗和高延迟的问题.最后通过试验与现有路由算法DBR、DBMR进行对比,结果表明提出的路由协议能耗更低,更适合水下节点间的通信过程.
