PRIORITY ORIENTED SCHEDULING IN CELLULAR SYSTEMS WITH DYNAMIC PACKET ASSIGNMENT

In this paper, we study the performance of channelized cellular systems when using dynamic packet assignment (DPA) based Medium Access methodology in the downlink. We present a near-distributed approach to resource allocation with a minimum level of co-ordination between base stations. We have implemented a priority based scheduling scheme at the base stations to provide Quality of Service (QoS) guarantees. We show through extensive simulation results that our scheduling model improves the delay performance of real-time traffic with no significant decrease in the throughput of the system as compared with first come first serve (FCFS) model. 1
