网络可靠性是网络性能评估指标的一个方面，对于网络系统级的性能评估有重要意义。该文通过构建随时间变化的表征网络节点连通性状态的关联矩阵，在节点故障和移动性变化的情况下，对自组网网络可靠性进行了研究，提供了一种自组网可靠性定量评价方法。通过大量的随机试验表明，该方法能有效验证自组网的可靠性。关 键 词 自组网; 评价; 关联矩阵; 可靠性Abstract The reliability of network reflects one aspect of network’s performance, it plays an important part in the evaluation of system performance. Is this paper, a new estimate index of network reliability is introduced and an incidence matrix is used to depict the connectivity of the network nodes in a dynamic network model. A determinant arithmetic of the network connectivity and a calculate method are presented to achieve reliavility evaluation for Ad hoc network. Simulation results through random trials indicate that the method presented in this paper is usable to validate the reliability of the dynamic Ad hoc network.Key words Ad hoc network; evaluation; incidence matrix; reliabi
