A QoS-Based Fairness-Aware Downlink Scheduling in LTE-Advanced

Abstract

Recent years, the demands of wireless networks in Taiwan grow fast because of users almost take a cam call or watch video streams on you tube. How to fulfill most users' demand under limited wireless internet resources situation becomes an important issue. In wireless networks resource management, the design of schedulers is the most important part. This paper proposed a scheduling scheme that meets most users' demands. This scheme distinguishes whether this connection is real-time or not and dealing it before it time out. If a user is located a cell edge, his demands may be rejected because of avoiding waste system resource. Besides Starvation and Fairness problems are also considered. There are no connections occupy resource for a long time or connections wait for a long time to be served to meet QOS(the quality of service). The experiment results will proof our method is efficiency than others.
