摘　　要：在水下通信系统中,仅仅考虑节点的强度来描述水下通信系统中各个节点的重要性是片面的,为了更好地对水下通信系统的节点重要性进行评估,提出了节点连通度这一指标对水下通信系统进行描述。对节点连通度的定义和方法进行了说明,并对水下通信系统节点重要性和失效方式进行了计算推导,得到水下通信系统节点信息被获取的概率的计算方法。通过对一个水下通信模型进行仿真,验证了节点连通度指标可以描述水下通信系统的生存性。In the underwater communication system,it is one-sided to describe the importance of each node in the underwater communication system only by considering the strength of the node.In order to better evaluate the importance of the node in the underwater communication system,this paper proposes the node connectivity.This indicator describes the underwater communication system,explains the definition and method of node connectivity,and calculates and derives the importance and failure mode of the underwater communication system node,and obtains the information of the underwater communication system node.The probability calculation method,by simulating an underwater communication model,verifies that the node connectivity index can describe the survivability of the underwater communication system.
