移动Ad Hoc网络中基于QoS的多路径路由协议研究

摘要

针对现有移动Ad Hoc网在大流量业务下无法提供高质量QoS保障的问题,通过推导证明提出了路径长度限制的路径稳定的约束关系,进而将QoS的判定因子引入一种确定性的最优权值约束路由算法进行实例化,并在该路由算法的基础上提出了基于QoS保障的多路径路由协议(MP-QAODV).通过仿真,验证了MP-QAODV协议在平均端到端时延、端到端数据分组投递率、归一化路由开销等方面优于AODV和AOMDV协议.%For the problem that the existing Ad Hoc network can not offer the high-quality of QoS under the large flow of data services,the relationship between path length and path stability are proved and proposed,and the QoS key element into a deterministic optimal weight constraints routing algorithm is introduced.Based on this routing algorithm,QoS-based multi-path routing protocol MP-QAODV is proposed.Through the computer simulates,it prove that the MP-QAODV owns better quality at the average end-to-end delay,packet delivery ratio,route control overhead,route discovery frequency than AODV and AOMDV.
