Since the IEEE 802.16 first standard was proposed in 2004 to provide broadband wireless service, the standard has not only been widely studied, but also broadly commercialized. The current IEEE 802.16-2009 standard document specifies five Quality of Service classes. As is typical with most standards, IEEE 802.16 does not require the use of a specific scheduler. In this paper, the authors first evaluate the performance of four popular schedulers. By analyzing the results, they highlight that no single scheduler type performs the best in all traffic situations; however, they shown that there exist the most favorable scheduler type in each situation.
