Priority Based Uplink Scheduler for IEEE 802.16 Networks
IEEE 802.16, the standard for fixed, portable and mobile Broadband Wireless Access (BWA) systems, is promising to support different classes of traffic with Quality of Service (QoS). The Medium Access Control (MAC) protocol defines a wide variety of mechanisms for bandwidth allocation and QoS provision. However, the details of how to schedule traffic are left unspecified. In this paper, the authors propose a scheduling strategy for uplink traffic. Simulation results show that the authors' scheme is capable to provide required QoS.
