一种适用于宽带无线多媒体网络的上行带宽分配方案

提出了一种适用于宽带无线多媒体网络的上行无线带宽分配方案。该方案将业务数据分为3种类型，即实时恒定速率业务、恒定变速率业务、非实时业务，针对不同业务对时延和带宽的不同需求，采取不同的方法获取上行带宽，较好地解决了多业务并发时的上行带宽分配问题，较传统技术提高了带宽利用率，减少了协议开销和传输时延。在详细描述算法的基础上，建立了对应的仿真系统对算法进行了验证。

Uplink Bandwidth Allocation Method for Broadband Wireless Multimedia Networks

A new uplink bandwidth resource allocation scheme for broadband wireless multimedia systems was pro- posed.In this new method,all services were differentiated by the three types:real-time invariable rate services,real- time variable rate services and non-real-time services.According to the different requirements of delay and bandwidth of different services,this method adopted different algorithm to allocate uplink bandwidth,successfully resolved the up- link bandwidth allocation problem for the simultaneous multiple services,and also reduced the protocol wasting and transmission delay.The detailed illustration of the algorithm was proposed and the performance was evaluated by ex- periments.
