摘　　要：无线Ad Hoc网络的应用环境以及与Internet的互连都要求其必须提供一定的服务质量(QoS)保证,QoS路由技术是在无线Ad Hoc网络中实现QoS的重要方法。本文对近年来国内外在无线Ad Hoc网络中的QoS路由技术方面取得的研究成果进行了全面的概括总结和分类,对资源预留路由、多径路由和跨层优化路由3类QoS路由协议进行比较分析,并且提出了QoS路由技术亟待解决的问题和今后的发展方向。The application environments and connecting with the Internet require that wiceless Ad Hoc networks should support Quality - of - Service （QoS） ,and QoS routing is one of the most important QoS mechanisms in wireless Ad Hoe networks. This paper comprehensively summarizes and analyzes the researches of recent years on the QoS routing,including resource reservation QoS routing, multi- path QoS routing,and cross- layer QoS routing. Based on the analysis, we deeply discuss the problems that must he resolved to support QoS in search in the future. wireless Ad Hoc networks,and point out the direction of the research in the future.
