Abstract :
We present two algorithms for transmitting the jittered constant bit rate (CBR) traffic on the upstream channel in broadband wireless access (BWA) systems: a calibration algorithm and a scheduling algorithm. The high priority CBR service class is used to transmit the voice traffic because of its stringent QoS requirements. Our design is aimed at supporting stringent QoS requirements and obtaining high utilization of the upstream bandwidth. Simulation results are presented to demonstrate the effectiveness of our algorithms in achieving high bandwidth utilization and the good traffic performance in terms of both cell loss ratio and mean queuing delay.
