An Efficient Qos Scheduling Algorithm for Ieee 802.16 Networks

Worldwide Interoperability for Microwave Access (WiMAX) is one of the most familiar broadband wireless access technologies that support multimedia transmission. IEEE802.16 Medium Access Control (MAC) covers a large area for bandwidth allocation and Quality of Service (QoS) mechanisms for various types of applications. Nevertheless, the standard lacks a MAC scheduling algorithm that has a multi-dimensional objective of satisfying QoS requirements of the users, maximizing channel utilization while ensuring fairness among users. So a novel Priority based Scheduling Algorithm using Fuzzy logic that addresses these aspects are proposed. The initial results show that maximum channel utilization is achieved with a negligible increment in processing time while keeping the priority intact. and fairness.
