【摘要】 针对现有多媒体通信卫星网络资源申请算法严重滞后于流量变化的缺点,提出一种基于流量预测的无线资源申请算法。通过引入记录因子实时记录资源分配结果,减少网络资源重复申请所带来的延时,并利用业务预测算法对多媒体卫星网络动态业务流进行流量估计,提高网络带宽分配效率。仿真结果表明,本文算法性能优于现有资源申请算法,具有良好的适应性。更多还原

【Abstract】 As the traffic deficiency in existing algorithms seriously lagged behind the increasing traffic, a resource request estimation algorithm based on traffic prediction is proposed in multimedia communications satecom. By introducing the recording operator into the algorithm to record the real-time allocation of resources, the duplication of network resources brought about by the application of the delay is reduced. Also the business forecasting algorithm is applied to do traffic prediction, so as to improve the bandwidth allocation efficiency. The simulation results showed that the algorithm proposed in this paper is greatly superior to other existing resource request algorithms in the adaptability.更多还原
