移动自组网是一种不需要依赖现有固定通信网络基础设施、能够迅速展开并投入使用的网络体系,随着移动自组网应用领域的日益扩大,能够提供端到端服务质量的QoS也显得越来越重要,QoS路由技术就是其中的核心技术和热点问题。本文首先指出了在移动自组网中实现QoS路由面临的困难,并指出了实施QoS路由的优点,然后从度量参数的选择、度量参数的组合方式、路由算法的选择及路由协议的维护四个角度介绍了QoS路由协议,其次介绍了目前QoS路由协议的研究现状,并对几种典型的QoS路由协议进行了分析及对比,在文章的最后指出了今后在移动自组网QoS路由协议中可能的研究方向。
Mobile ad hoc network is a kind of network system that can be expanded and put into use quickly without relying on the existing infrastructure of fixed communication network. With the growing application area of mobile Ad Hoc network, QoS can provide end-to-end QoS It seems more and more important, QoS routing technology is one of the core technologies and hot issues. This paper first points out the difficulties in implementing QoS routing in mobile ad hoc networks and points out the advantages of implementing QoS routing. From the point of metric parameters selection, the combination of metric parameters, the selection of routing algorithms and the maintenance of routing protocols Secondly, the current research status of QoS routing protocol is introduced, and several typical QoS routing protocols are analyzed and compared. At the end of the article, the paper points out the possibility of using QoS routing protocols in mobile ad hoc networks Research direction.
