摘要
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 temporary autonomous system of mobile nodes with wireless transmitters and receivers. With the development of multimedia service in the wireless communications, QoS has become more and more important in mobile ad hoe network, while QoS routing technology is the core technology and the focus issue of it. In this paper, the difficulties of QoS routing in mobile ad hoe network are indicated and typical QoS routing procols are analyzed and compared in detail. Several newer QoS routing protocols are also introduced. The development of QoS routing protocols is prospected in the end.
