Fuzzy based quality of service analysis of scheduler for WiMAX networks

Abstract

WiMAX is an upcoming technology gaining grounds day by day that has inherent support for real and non real applications. The rise in number of real time application with popularity of mobile phones always tests scheduler performance of broadband wireless systems like WiMAX. Distribution of resources in such networks has always been a challenging phenomenon. This problem can be solved if scheduling decision is based on traffic conditions of incoming traffic. This paper proposes an application of fuzzy logic by virtue of which an intelligent system for distribution of resources has been defined. The system works as adaptive approach in granting bandwidth to those traffic classes that has relatively higher share of incoming traffic in its queues. The results demonstrate significance of the proposed method.
