Transmission of multicast traffic (such as video, data and voice services over World Wide Interoperability for Micro Wave Access “WiMAX” aims to make multicast traffic available to users anywhere, anytime and on any device. The major challenges of transmitting wireless traffic over WiMAX network through convention multicast schemes are throughput fluctuation (Variations) among the subscribers within the network coverage, unfair distribution of network resources, delay, delay jitter and packet drop because they are placed in different locations from the Base Station. These inefficiencies are as a result of different fading and path losses in time-varying wireless channel experience by the Subscribers. Scheduling algorithms are mainly responsible for utilization of available resources that are obtained in the network in order to ensure the desire quality of service, among those scheduling algorithms are Round Robin, Max Rate, first in first out, Maximum Throughput, proportional fairness and weighted fair queuing etc. This paper surveys various scheduling algorithms for maximization of network throughput, fair distribution of resource, minimize packet loss and delay in WiMAX. Performances and limitations of some of the previous works are identified. Finally, future research directions to improve on some of the observed inefficiencies are discussed.
