Abstract

The medium access control (MAC) protocol is one of the key components for providing quality of service (QoS) in wireless ATM (W-ATM) networks. In this paper, we propose a hierarchical scheduling scheme coupled with fair queueing algorithms with adaptive weights. This scheme is intended to be applicable to a TDMA/TDD-based MAC protocol. Specifically, the performance of the fair-queueing algorithm using fixed weights and adaptive weights are investigated. Simulation results show that the proposed hierarchical fair-queueing scheduling with adaptive weights (HAW) can yield a lower cell transfer delay and higher channel utilization while maintaining fairness among multiple users
