Abstract—This study aims to enhance the capacity of the mesh mode WiMAX network by designing an efficient and fair scheduling algorithm, which resolves the bandwidth contention problem and determines the transmission order for end-users. It is also analyzed the algorithmic complexity of different existing WiMAX network scheduling approaches and demonstrated their lack of fairness. In this paper, therefore, we proposed new variation of a centralized scheduling algorithm for IEEE 802.16 mesh mode standard that is able to schedule the nodes efficiently while ensuring fairness. The algorithm is also providing an equal amount of bandwidth and handling extensible traffic without interference to the users in the same range of a networking coverage area. We then provided a complexity analysis for our proposed algorithm followed by a comparison with the complexity of the existing approaches. We also evaluated the proposed algorithm on a well-known networking simulation to ensure that it satisfies the fair scheduling issue requirements. The empirical results indicate that the proposed algorithm achieves a significant improvement in performance over existing scheduling algorithms.
