摘要
针对AdHoc网络管理系统，提出了一种可靠性评估算法，首先确定AdHoc网管系统可靠性三要素，然后利用最小定点割集确定AdHoc网络中的重要区域，同时根据生成树算法确定各个网管子系统的权重系数，分析AdHoc网络管理系统特点确定失效判据，依据失效判据进行可靠性建模，选择合适的可靠性模型，从而可以计算出AdHoc网络管理系统的可靠度。最后通过实例说明某AdHoc网络管理系统的可靠性评估。
An algorithm of reliability evaluation is brought forward fo Ad Hoe Networks management system. Firstly three key factors of Ad Hoc network management system reliability is defined. Then important area is determined by minimum vertex cut set. The weight coefficient of each subnet management system is drawn by Spanning Tree Protocol. Disabled criterion is defined by analyzing the characteristic of Ad Hoc Networks management system. Reliability model is built according to disabled criterion and is selected. The reliability of Ad Hoe Networks management system is computed. Lastly the reliability evaluation on Ad Hoc Networks management system is illustrated by examples.
