移动Ad Hoc网络中基于QoS的多路径路由协议研究

Study of Ad Hoc Network Multi-Path Routing Protocol Based on QoS

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.
