在移动Ad Hoc研究中,QoS研究重要方面,虽然在传统网络中多路径的路由协议研究已相当成熟,但是大多数Ad Hoc路由协议都是基于单路由的,而且并不能很好的支持QoS约束。本文对现有DSR的协议的基础上,加入多径使其满足一定的延时约束,提出了一种移路径QoS路由协议,并给出了正确性验证及复杂性分析,并在NS2平台下对该改进后的协议进行了仿真实验和分析。仿真结果表明,该路由协议减少了路由重建数量,有效的增加了Ad Hoc网络的吞吐率,降低了延时从而有效地提高了网络性能。最后,对下一步改进工作也作简单介绍。
In the research of mobile Ad Hoc, QoS studies the important aspects. Although the research of multipath routing protocol is quite mature in traditional networks, most Ad Hoc routing protocols are based on single routing and do not support QoS constraints well . In this paper, based on the existing DSR protocol, we add multipath to meet some delay constraints, and propose a path QoS routing protocol, and give the correctness verification and complexity analysis, and in the NS2 platform The improved protocol is simulated and analyzed. The simulation results show that the routing protocol reduces the number of route rebuilds, effectively increases the throughput of Ad Hoc networks, reduces the delay and effectively improves the network performance. Finally, the next step to improve the work also made a brief introduction.
