A Review on IEEE 802.16 Standards and their Comprehensive Analysis on WiMAX

IEEE protocal 802.16 (d) i. e fixed wimax provides to offer mobile broadband services even at a vehicular speed of up to 120 km/hr. In wimax quality of services provided through scheduling of the different types of service classes like BE, ertPS, nrtPS, rtPS and UGS. Scheduling algorithm are round robin, Weighted Round Robin (WRR) and Weighted Fair Queuing (WFQ). The performance is observed at end-to-end delay, throughput and packet delivery ratio among 2 to 10 number of nodes.
