摘要
移动自组织网络(MANET,Mobile Ad hoc Network)是一种不依赖固定基础设施且不需要中心控制的动态无线网络。由于其开放自治的无线网络环境及无中心、动态拓扑等特性,导致MANET无法保障通讯的持续性,同时容易受到各种安全攻击。因此相对于传统网络,MANET在网络的可靠性上存在很大的局限性。综合考虑了影响MANET可靠性的两大因素,即节点移动性和安全攻击,提出了多维MANET可靠性模型,并对模型结果进行了实验分析,进一步指出了影响MANET系统可靠性的关键参数。
Without infrastructure,Mobile Ad Hoc Network（MANET） is a kind of self-organized and dynamic wireless communication network that is lack of any centralized control.These characteristics make it vulnerable to communication continuity and security attack.Comparing with traditional network,MANET has great limitation in network reliability.Many researches have been focused on two main factors of reliability or reliability model,which influence the reliability of MANET.Therefore,this paper proposed a multiple dimensional reliability model,which considers both movement and security attack,for MANET.Furthermore,the experimental analysis of the model was given.According to the result of experimental analysis,the key factor of MANET reliability was presented.
