Admission Control Based on WRR in WiMAX Networks

With the diversity of services and the need of different traffic classes in wireless networks, WIMAX technology (Worldwide Interoperability for Microwave Access), has been developed as a broadband wireless access technology based on IEEE standard 802.16. Indeed, this technology is able to mix real time and non real time services with the definition of service classes. To improve the admission rate of the different classes when implementing the admission control component, we propose in this paper a traffic scheduling based on WRR policy and a new mechanism to handle the rejected requests. Finally, we provide the Markov Chain based modelling of our solution and compute thereof primary performance evaluation results.
