【摘要】 现有的调度算法(包括有线和无线网络)大多模拟GPS(通用处理器共享)流体公平队列模型来调度数据包。无线网络环境中的某些用户可能会因为位置相关的信道错误而暂时不能接受服务,此时GPS模型不能有效地工作。根据无线网络的特点,提出了一种新型的流体公平队列模型W GPS。W GPS合理的机制对未接受服务的用户在后续时间进行补偿。通过分析表明,W GPS比GPS更适合于无线网络环境。更多还原

【Abstract】 Most existing algorithms schedule packets by simulating GPS(a fluid fair queuing model).However,some users in wireless network cannot be served because of the location-dependent channel error and GPS cannot work effectively.According to the characteristics of wireless network,WGPS(a new fluid fair queuing model) is put forward.Channel error users can be compensated by proper way in this model.The analysis shows that WGPS is more applicable than GPS in wireless network.更多还原
