摘　　要：Ad Hoc网络是一种由移动节点组成、拓扑结构动态变化的自组织网络,在Ad Hoc网络中实现带有QoS约束的路由是当今研究的重要问题。QoS路由协议算法中最主要的三个方面是:QoS参数的选取,对单向链路的支持和路由协议的多播功能。本文首先介绍了应用较广的几类QoS路由协议的算法,接着选取了以上三个方面中几个典型的QoS路由协议,详细介绍了它们的特点以及算法思想,并对协议的性能进行了具体分析,分析结果对研究QoS路由协议有一定的指导意义。Ad Hoc network consists of a collection of mobile nodes, dynamically creating a self-organizing network. In Ad Hoc network research, it is an important problem that how to make routing with QoS constrained. Three main aspects of QoS routing protocol algorithm are QoS preference, support of unidirectional link and multicast functions. This paper introduces the algorithm of some QoS routing protocols which are applied widely, then itemizes the trait as well as the algorithm of the mentioned kinds of protocols,and analyzes the protocols＇ performance concretely, so the conclusion will have an instructional meaning to the research in QoS routing protocol.
