移动Ad Hoc网络QoS路由协议研究

The Study of QoS Routing Protocols in Mobile Ad Hoc Networks

移动AdHoc网络以其灵活、健壮等特性正成为无线网络研究特别是军事研究的一个热点,但其自身的移动性、多跳性和网络带宽的受限性等使传统的路由技术已不再适合。文章首先介绍AdHoc网络的特点及面临的问题。然后对当前AdHoc网络的QoS主要路由协议进行了详细的分析与研究,并从路由机制、单向链路的支持、多播功能、QoS参数选择以及节能等方面进行了比较和分析。最后探讨了今后AdHoc网络路由技术的最新发展动态和研究方向。

With the flexibility and robustness,Ad Hoc wireless network has become the researching hot spot of wireless network,especially in military field.While due to the mobility,multihopping and the constraints of bandwidth,the traditional routing methods have not been appropriate.In this paper,firstly the characteristics and problems of Ad Hoc network are introduced.Then,this paper analyses QoS routing protocols that are being mostly researched currently in detail in mobile Ad Hoc networks.It also compares and analyzes them in different aspects,such as muting mechanism,the support of unidirectional link,multicast functions,QoS preference and power-saving.Finally,the latest development and researching orientation of Ad Hoc wireless network are introduced.
