移动自组网是由一组带有无线收发装置的移动节点组成的一个多跳的临时性的自治系统。随着无线通信中多媒体业务的增加,在移动自组网中提供QoS(Quality of Sevice服务质量)保障具有越来越重要的意义,而QoS路由技术则是其中的核心技术和热点问题。文章指出移动自组网QoS路由的困难,对移动自组网典型QoS路由协议进行了详细的分析与比较,并对几种较新的移动自组网QoS路由协议进行了介绍,末了对移动自组网QoS路由协议的发展进行了展望。
Mobile ad hoc network is a multi-hop ad hoc autonomous system composed of a group of mobile nodes with wireless transceivers. With the increase of multimedia services in wireless communication, it is more and more important to provide QoS (Quality of Service) guarantee in mobile ad hoc networks. QoS routing technology is one of the core technologies and hot issues. This paper points out the difficulties of mobile ad hoc network QoS routing, analyzes and compares the typical QoS routing protocols of mobile ad hoc networks in detail, and introduces several newer mobile ad hoc network QoS routing protocols. Finally, The development of network QoS routing protocol is prospected.
