“…In the second stage, output of the two WRR schedulers are enqueued in two queues F1 and F2, packets of these queues are managed by a priority PQ scheduler which gives higher priority to real time stream (stored in F1) which are more constringent in term of throughput and delay than the non-real time traffic (stored in F2) which are less time sensitive. The simulation results from [4] is the combination that it is recommended is to use TP as a selection traffic granularity method with MAXSNR as a mapping slot strategy after processing traffic by proposed hybrid scheduling block.…”

Wireless Man or WiMAX, where WiMAX stands on Worldwide Interoperability for Microwave Access, is one of the latest technologies in the Wire-Less World. The main goal of WiMAX is to deliver wireless communications with quality of service in a secured environment. Unlike wireless LANs, WiMAX networks incorporate several qualities of service (QoS) mechanisms at the Media Access Control (MAC) level for guaranteed services for data, voice and video. Its Mobility feature makes it different from the other IEEE 802.16 protocols which was based on Static WiMAX and provided the Wireless communication at fixed locations. This paper deals with the key features of the IEEE 802.16e scheduling algorithms at MAC layer, their classification and their survey in which several authors have already done the research in this field. In addition to ensuring feasible algorithm complexity and system scalability, the purpose of scheduling algorithms also includes optimal usage of resources, to assure what the QoS guarantees, to maximize good throughput and to minimize power consumption. General TermsCross layer scheduling, WRR, WFQ.
