移动AdHoc网络环境下基于风险的高效可靠的服务组合方法研究
在移动AdHoc网中,由于节点以及网络拓扑结构的动态性,服务组合性能往往比在静态网络环境中更不稳定。为了提高服务组合的可靠性,大量的研究工作关注最小化服务组合的中断次数以及服务组合的重组.而对于在服务进行组合之前就预先判断服务的可靠性的研究较少。本文旨在利用移动预测技术结果,在服务组合使用之前寻找具有较低失效风险的服务组合方案.提出了失效风险模型以衡量服务组合的可靠性,并且在该模型的基础上设计了3种算法用于求解服务组合。本文还进行了相应的实验来评估所提出算法的特点。...

In order to improve the reliability of service composition, current research works mainly focus on minimizing times of interruption and the services re-composition, and pay little attention to estimating the reliability before composition. By taking advantages of the mobility prediction for mobile nodes, this paper proposed approaches to find the service composition scheme with low failure risks bef |
