摘　　要：在已有的带宽分配算法的基础上,引入加权准则对竞争的数据流进行带宽分配,该算法工作紧密结合无限局域网的MAC层协议DCF,由此保证带宽分配的公平性和每条流的最低带宽需求。使用NS仿真进行性能评价,实验表明,该算法在满足数据流的最低带宽需求的同时,提高了系统吞吐量。该文提出的算法尤其适合单跳Adhoc多媒体传输。This paper introduces a new simple weighted max-min bandwidth allocation method based on main current allocation technology. The algorithm is coupled closely with DCF, in order to ensure the fairness and minimum bandwidth requirement for each flow. Simulations are performed using NS and the results show that the new method can not only satisfy each flow＇s minimum bandwidth requirement, but also increase the system throughput. The new method especially adapts single-hop networks in multimedia transmission.

关 键 词：带宽分配 最大最小公平性 加权
