一种无线/移动网络二级结构自适应公平调度算法
首发时间:2007-12-22
摘要:本文研究了无线/移动网络环境下自适应公平调度模型,讨论了服务区分的必要性和无线/移动网络调度补偿方法,设计了一种二级结构的服务区分自适应公平调度算法(TWFS),算法能够区分不同服务类型,公平分配网络资源。对于链路造成的暂时性服务中断给予了多级服务补偿,并通过分组级的公平资源分配,保障服务质量和流队列的平滑降级。

A Two-level Fair Scheduling Algorithm in Wireless/mobile Network
Abstract:In this issue, we study on the fair scheduling model in wireless/mobile environment, discuss the necessity of Diff-Serve and compensatory scheduling mechanism, devise a two-level wireless fair scheduling algorithm (TWFS) which differentiates service types and allocates network resources fairly. As for the contemporary service intermittence due to link failure, we make service compensations at link level and packet level. The packet level fair resource allocation ensures the graceful degradation of service quality.
Keywords: wireless/mobile network, self-adaptive control, queue management, resource allocation
