| 摘 要： | 随着人们对移动自组网(ad hoc网络)研究的深入,服务质量(QoS)已经成为了当前的研究热点之一.为了在ad hoc特殊的网络中提供对QoS的支持,必须设计一种针对流的高效的接纳控制算法.通过分析无线信道的特点,提出了估算本地可用带宽和流可用带宽的方法,同时对流的带宽耗费进行了推导,解决了实现接纳控制必须解决的关键问题,提出了一种基于QoS的分布式接纳控制算法.仿真实验证明,接纳控制算法应用到传统的路由协议(比如AODV)中,性能将会大大提高,并且更适合于实时业务的传输.

| Abstract: | Along with the deep research on ad hoc networks, quality of service(QoS) has become one of the hot topic at present. In order to provide a backup for QoS in the special network of ad hoc, designing an effective admission control algorithm aiming at flow is necessarily. By analyzing the characteristics of wireless channel, this paper proposes a method for estimating the a vailable local bandwidth and flow bandwidth. Besides, it also deduces the bandwidth consumption of flows, solves the key problems of imple... |
