WiMAX is based on the standard IEEE 802.16e-2009 for wireless access in metropolitan area networks. It is one of the solutions for 4G IP based wireless technology. WiMAX utilizes orthogonal frequency division multiple access which also supports multicast and broadcast service with appropriate modulation and coding scheme. Presently, scheduling and resource allocation algorithm in opportunistic layered multicasting provides multicasting of layered video over mobile WiMAX to ensure better QoS. Initially, the knowledge based allocation of subcarriers is used for scheduling.
