| Abstract: | Scheduling algorithm is an important tool to guarantee QoS for classification service in broadband wireless access （BWA）. An improved hierarchical scheduling services algorithm for IEEE 802.16d broadband wireless access systems in TDD mode is proposed. The simulation results show that the proposed algorithm has a better performance than other similar kind of algorithm in terms of throughput, average delay, drop probability and fairness to UGS, rtPS, nrtPS and BE traffic. |
