A Comprehensive Survey of Downlink Scheduling Algorithms in WiMAX
Abstract: WiMAX (Worldwide Interoperability for Microwave Access) is a telecommunication technology that offers an internet access through the transmission of wireless data as Wi Fi or other broadband providing techniques, but with higher speed and an alternative to wired broadband like cable, modem and DSL and support real time and non-real time services with high QOS (Quality of Service). The high QOS loads a big challenge on resources allocation to accommodate large number of users demanding several services with different QOS competing for limited capacity in the network. The high QOS is supported by scheduling mechanism. The standard leaves the details of scheduling different services with their QOS as an open issue for researchers and manufacturers to implement. Therefore number of algorithms downlink and uplink has been proposed. This paper provides a comprehensive survey of downlink scheduling algorithms, their aspects, methodology strength and limitations.
