An Efficient Study of Scheduling Algorithms with Friedman Test in WiMAX Networks

Abstract

In this paper, we propose a scheduling strategy for various IPTV services traffic (HD-TV, SD-TV, Web-TV and Mobile-TV) over 802.16j networks. Our 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.
