Abstract:
Over the past few years, there has been a rapid growth of new services offered to end users on the Internet, such as online video games, video conferences, and multimedia services. WiMAX networks are one prominent viable solution for wireless broadband access that provides last-mile access to the Internet. To satisfy the Quality of Service (QoS) requirements of the applications in an acceptable way, an efficient scheduling algorithm is needed. In the literature, attention was focused on throughput and delay only. Jitter, though of great significance, was not taken into account. In this paper, we consider jitter, in addition to throughput and delay, in order to formulate a three-term dynamic weight function. The jitter and delay terms, in particular, are weighted by specific weighting factors, whose values in real-time applications are different from those in non-real-time applications. Simulation results are obtained by OPNET, and it is shown that the proposed algorithm outperforms two famous previously published algorithms.
