摘要

This paper presents a mobile-assisted frame-based PRMA (MAF-PRMA) protocol, which optimizes random access control between heterogeneous traffic aiming at more efficient voice/data integrated services in dynamic reservation TDMA-based broadband wireless access networks. In order to achieve a differentiated quality-of-service (QoS) guarantee for individual service plus maximal system resource utilization, the MAF-PRMA independently controls the random access parameters, frame-by-frame basis. In addition, we have adopted a mobile-assisted random access mechanism where the voice terminal readjusts a global permission probability from the central controller, to handle the 'fair access' issue resulting from distributed queuing problems inherent in the access network. Our extensive simulation results indicate that the MAF-PRMA achieves significant improvements in terms of voice capacity, delay, and fairness over most of the existing MAC schemes for the integrated services.
