Fundamental Analysis of Two-layered Scheduling Algorithm for a Wireless Packet System

Third generation mobile communication systems are currently spreading worldwide and the associated high speed data services are being widely utilized by the public at large. As more rapid services are established, the provision of wider band wireless systems is expected in next generation mobile communication systems. Wireless packet technology has recently been attracting considerable attention for its high throughput performance and is required for QoS (quality of service) control, given its applicability for all type of services, non-real time as well as real-time. In this paper, we propose a new packet scheduling algorithm for wireless communication systems. It has a two-layered structure, to guarantee QoS and also high frequency efficiency. We estimated the performance of our proposed algorithm using a computer simulation. The results show that the proposed algorithm can achieve a higher throughput and improved delay performance compared to conventional algorithms, such as maximum CIR, proportional fairness and round robin
