Abstract
For provisioning the best effort service, the IEEE 802.16 Wireless MAN standard employs a MAC scheme based on reservation ALOHA. In the MAC scheme, a subscriber station, after attempting a resource request, waits for a resource grant during a prescribed period rather than an explicit acknowledgement. In this paper, we propose a MAC scheme for improving delay performance, where we control the lifetime of a request to prevent excessive grants and distribute residual resource according to a round robin. Simulation results show that the proposed scheme significantly improves the mean delay performance.
