A Heuristic Strategy for IEEE 802.16 WiMAX Scheduler for Quality of Service
Overview The advent of Broadband wireless promises quality communications over the wireless channel. The 802.16 standard is expected to arise as the main Broadband Wireless Access (BWA) Technology, providing high-speed data access to subscribers. In this paper, an important part of such a network, the MAC scheduler, is investigated. Although IEEE 802.16 defines specific Quality of Service (QoS) traffic flows, scheduling of heterogeneous applications is left open for research. A heuristic approach is followed to propose a QoS strategy. In the proposed strategy, Call Admission Control (CAC) is implemented for high-priority traffic so as to overcome the problem of starvation of network resources. Moreover different contention minislots allocation strategies, for low-priority traffic, are investigated.
