摘　　要：移动Ad Hoc网络(MANET)的动态拓扑结构使网络可靠性评估较为困难,为此提出一种基于连接矩阵的MANET可靠性评估方案.首先,确定网络中的源-终节点对和中继节点.然后,根据节点间欧式距离和通信范围来检测中继链路状态,并构建连接矩阵.最后,根据连接矩阵判断网络连接性,以多轮连接性的均值作为网络的最终可靠性.仿真实验中,评估了节点移动模型、网络大小、节点数量和通信范围对网络可靠性的影响,能够为网络设计者提供有力的依据.The dynamic topology of mobile Hoc Ad network（MANET）makes it difficult to evaluate the reliability of the network,so a reliability evaluation scheme for MANET based on connection matrix is proposed.First,the source-terminal node pair and relay nodes in the network are determined.Then,the relay link state is detected according to the Euclidean distance between nodes and the communication range,so as to construct the connection matrix.Finally,the network connectivity is determined based on the connection matrix,and the average of connectivity value in some rounds is regard as the reliability of the network.In the simulation experiment,the influence of the node mobility model,the network size,the number of nodes and the range of communication on the network reliability is evaluated,which can provide a strong basis for network designers.
