Abstract—This paper proposes a new scheduling algorithm
for IEEE802.16 Broadband wireless Metropolitan Area
Networks in TDD mode. The proposed algorithm focuses on an
efficient mechanism to serve high priority traffic in congested
networks. A detailed simulation study is carried out for the
proposed scheduling algorithm and its performance has been
compared with some known algorithms such as Proportional
Fairness (PF), Adaptive Proportional Fairness (APF) and
Round Robin (RR). For performance evaluation and
comparison with existing algorithms, we used OPNET 14.5
modeler simulator. The results show that the proposed
algorithm is capable of dealing with different users’
requirements under congestion conditions.
Index Terms—QoS, OFDMA, scheduling algorithms,
proportional fairness, wimax.
