Abstract

IEEE 802.16 broadband wireless access standard specifies four types of services to satisfy the quality of service (QoS) requirements of multimedia applications. How to design a scheduling algorithm is an open issue. Manufacturers can implement their own efficient scheduling algorithm depending on their requirement. There are a lot of scheduling algorithms that have been proposed. No matter these scheduling algorithms propose a hierarchical structure with strict priority or one-level scheduling mechanism, which is based conceptually on the round-robin approach, they do not consider an important factor: fair. The authors introduce a fair strategy algorithm for IEEE 802.16 broadband wireless access standard. The proposed algorithm applies a fair strategy to utilise the system bandwidth, achieve the QoS requirements of high-priority service flows and reduce starvations of low-priority service flows. The simulation studies show that the proposed scheduling algorithm provides a flexible way to utilise the system bandwidth.
