  Abstract

This paper presents a fuzzy-based intelligent medium access controller (FiMAC), which can optimize the random access control for providing voice/data integrated services in the dynamic reservation TDMA-based broadband access networks. In order to achieve the design objective of differentiated quality-of-service (QoS) guarantee for individual service and the maximal system resource utilization, the FiMAC intelligently and independently controls the random access parameters such as the lengths of random access regions dedicated to respective service traffic and the corresponding permission probabilities using fuzzy control technique frame by frame. In addition, to handle the fair access issue due to distributed queueing problem inherent to access network structure, we adopt the mobile-assisted random access mechanism where the voice terminal readjusts global permission probability from FiMAC to its optimal value. Our extensive simulation results indicate that the FiMAC is well coordinated with a mobile-assistance such that significant improvement is achieved in terms of voice capacity, delay, and fairness over most of the existing MAC schemes for the integrated services.
