“…Each queue is serviced in a round robin order according to its weight. The queue with the highest priority weight takes to process more packets [6], [10]. However, the proposed mechanism uses WRR scheduling technique for two reasons, first, it allows avoiding the problem of resource starvation for lower priority classes, and the second, it gives the QoS guarantee in high-priority classes.…”

In this paper, we evaluate and compare our scheduling strategy for various IPTV services traffic over 802.16j networks with several scheduling algorithms such as Strict Priority algorithm (SP), Weighted Round Robin (WRR), and Modified Dynamic Weighted Round Robin (MWRR). The proposed scheme adapts dynamically the scheduler operation to according queue load and QoS constraints. In particular, the proposed mechanism gives more priority to HD-TV and SD-TV traffics by using two schedulers. The proposed scheduling algorithm has been simulated using the QualNet network simulator. The Friedman test has been used to address some significant issues of the analysis to compare the proposed scheme with the others scheme. The experimental result and analysis show that the proposed scheduler schemes outperform the traditional scheduling techniques for rtPS traffic that allows ensuring QoS requirements for IPTV application.

“…As mentioned by [18], no single inheritance schedulers that can fulfill all the QoS requirements of the WiMAX network applications. The EDF+WFQ+FIFO scheduling algorithm was proposed to provide low-delay and packet loss for real-time applications [19].…”

“…Their conclusion is that no algorithm dominates in all criteria such as average throughput or delay, frame utilisation, request honouring, or packet loss minimisation. However, the work of Ali, Dhrona, & Hassanein, H. (2009)) is not application specific and given the distinct possibility that WiMAX may dedicated to media services, further study is merited. Kim & Yeom, 2007 propose an uplink bandwidth allocation scheme for best effort TCP streams.…”

“…However, this is not straightforward because the frame types in use can vary according to the codec profile. Ali, Dhrona, & Hassanein, H. (2009) try to survey all types of UL bandwidth allocation algorithm and evaluate these algorithms with respect to their abilities to support multiple classes of services and to optimise bandwidth utilization. Their conclusion is that no algorithm dominates in all criteria such as average throughput or delay, frame utilisation, request honouring, or packet loss minimisation.…”

IEEE 802.16e (mobile WiMAX) uplink behavior is a relatively neglected area of investigation, but emerging interactive media services have highlighted the need for closer investigation of uplink issues. In this simulation study of uplink queue management, media streaming by TCP-Friendly Rate Control (TFRC) was found to offer advantages. However, temporal behavior of the queuing disciplines exhibits oscillations in buffer occupancy with build-up of delay during video streaming. The paper suggests a possible remedy lies in the choice of the more complex H.264/AVC Main profile, though this will impact upon mobile devices. It was also found that WiMAX video delivery is sensitive to choice of transmission frame size.
