An Optimal Bandwidth Resource Utilization Scheme in IEEE 802.16m Based Networks

The IEEE 802.16m based broadband wireless access is a brand-new technology to provide high speed and wide range communications for wireless users. However, how to exploit the optimal utilization of the radio frequency bands resource in such networks is a big challenging issue as it covers the radio channel capacity optimization, channel bandwidth utilization optimization and utilization performance analysis. In this regarding, we first propose a novel scheme to exploit the optimal channel transmission capacity based on the time varying state of each radio channel. Then we design an effective channel usage scheme to fully utilize the channel transmission bandwidth with respect to user's requirements. Next we also present a scheme to make the performance analysis on the proposed channel utilization scheme with respect to various metrics. Experiment results validate the efficiency and efficacy of the proposed schemes.
