Hierarchical fair-queueing for W-ATM

We propose a MAC protocol which is based on a hierarchical fair-queueing algorithm with adaptive weights (HAW). A TDMA/TDD based centralized W-ATM network is considered. The performance of fair-queueing algorithms using fixed weights and adaptive weights are investigated. Simulation results show that the proposed hierarchical scheduling can yield a lower cell delay and a higher channel utilization while maintaining fairness among multiple users.
