Mobile WiMAX's scheduling service is a key factor in Radio Resource Management (RRM) in realizing Quality of Service (QoS). The choice in scheduling algorithm for Mobile WiMAX base stations, albeit outside of the scope of the standard, critically impacts the performance and robustness of Mobile WiMAX networks. This paper provides an in-depth study of four major scheduling algorithms: Round Robin (RR),...
IEEE 802.16e-based Mobile WiMAX has gained considerable popularity recently. However, there is no current simulation model that provides feature completeness and performance accuracy. In this paper we propose the design and implementation methodology of a complete, accurate, realistic and versatile simulation model to support Mobile WiMAX for the NS-2 simulation platform. In the proposed simulation...
In this paper, a novel distributed medium access control (MAC) protocol is proposed so as to resolve the inherent problems in the IEEE 802.11 when employing the multiple-input multiple-output (MIMO) links. Currently, IEEE 802.11 based networks have become a de facto industry standard and have been used ubiquitously in business and in our daily lives. However, great challenges exist when they are applied...
