| 摘 要： | MANET的节点资源受限等特点给QoS路由设计提出了诸多挑战。在研究无线网络流量特性的基础上，提出了基于自相似特性的链路测量及QoS路由协议（Link Prediction based on self-similarity and QoS Routing Protocol，LPQRP）。LPQRP协议使用小波分析方法估计自相似特性唯一参数Hurst值，并利用Hurst值对网络性能进行估计，以测量结果作为QoS路由约束条件，以此方式优化了路由选择，提高了测量精度，有效提高了路由QoS保证。给出了LPQRP协议的设计过程，提出抖动因子等机制进一步完善了LPQRP协议。仿真结果显示，LPQRP协议能很好地适应MANET特性，有效优化数据传输路径，均衡网络资源，提高了网络的健壮性，减少了资源损耗。

| Abstract: | Great challenges to design the QoS routing protocol have been brought because of the characteristics of MANET such as node resources constraints.In this paper,the characteristics of wireless network traffic are analyzed and Link Prediction based on self-similarity and QoS Routing Protocol(LPQRP) are put forward.LPQRP estimates Hurst parameter by wavelet analysis,measures network traffic by Hurst values and solves measurement problems of multi-constraint QoS routing.LPQRP optimizes routing selection,enhances measure accuracy and provides the guarantee of QoS.Routing protocol designing and routing optimization policy based on jitter factor and so on are also discussed.The simulation result shows that LPQRP could adapt the characteristics of MANET,optimize the routing of data transferring,balance network resources and reduce network latency and bandwidth consumption. |
