Performance Evaluation of 1xEV-DO Rev. A System with a Per-User Throughput Based Scheduling Algorithm

Abstract

As the demands for wireless data services have increased, various packet services should be supported satisfying the different quality of service (QoS) requirements. We propose a per-user throughput based scheduling algorithm to support both fairness among users and different QoS requirements. Link-level and system-level simulators for the 1xEV-DO rev. A system are developed for performance evaluation. Through our system-level simulator, the performance of the proposed scheduling algorithm is compared with that of other three conventional scheduling algorithms in terms of fairness, per-user throughput, and system throughput. The result shows that the proposed scheduling algorithm yields the best performance result in terms of fairness. The proposed scheduling algorithm can be utilized to support both fairness among users and different QoS requirements for various packet services in wireless data communications
