Ad Hoc网络中QoS保障技术研究进展及展望

综述了Ad hoe网络中QoS保障方面的研究现状，描述和分析了目前在Ad hoc网络QoS中的QoS路由，QoS信令，MAC层QoS保障策略，动态自适应等几个主要研究领域所取得的一些成绩，同时也指出了其中所存在的一些问题及未来的研究方向。

Development and Prospect of the Supported QoS in Ad Hoc Networks

The application environments require that wireless ad hoc networks should support Quality-of-Service(QoS).In a wireless ad hoc network,supporting quality-of-service is very difficult because of the inherent characteristics of wireless channel and the frequent change of network topology.This paper comprehensively summarizes and deeply analyzes the researches of recent years on the QoS routing,QoS signaling,and media access control(MAC) mechanism,adaptive service adjusting and dynamic resource management in wireless ad hoc networks.Based on the analysis,this paper deeply discusses the problems that must be resolved to support QoS in wireless ad hoc networks,and points out the direction to the research in the future.
