Based on the in-depth analysis of the interaction patterns between the components of software system in architecture, this paper illustrates that the association among them is complex and usually changeable during the running period. So we assume the interactions between two adjacency components are grouped into a single connector, which can be used to analyze the influence of components assembly on the survivability for software architecture. The survivability of the components assembly is mapped into the connectivity of graph model. We also bring forward a simplicity method to calculate and quantify the survivability of architecture that could provide a more usable model for designers to evaluate the architecture.
Mobile Ad Hoc Network(MANET)网络的路由行为依赖于开放环境下自治移动节点间的相互合作。在对MANET路由信任关系及其特性进行分析的基础上,将节点的路由信任度量表述为基于转发行为经验的二项事件后验概率计算问题,利用概率模型解决节点的主观路由信任度量与数学评价问题,实现路由信任关系的量化与预测。以此为基础,将MANET信任路径转化为路由参与节点信任的合成,从而将端到端信任路由选择转化为最大生成树的求解问题,实现了信任路由的度量与选择。
