| Abstract: |
A dynamic reservation/allocation time division multiple access (DRA-TDMA) control protocol that extends the capabilities of asynchronous transfer mode (ATM) networks over the wireless channel is proposed. DRA-TDMA combines the advantages of distributed access and centralized control for transporting voice, variable bit rate (VBR), available bit rate (ABR), and unspecified bit rate (UBR) traffic efficiently over a wireless channel. The contention slots access for reservation requests is governed by the slotted Aloha protocol which based on two groups of mini-slots, one for real-time services (with highest priority) and the other for non-real time services (with lowest priority) to improve the quality of service (QoS). DRA-TDMA also features an integrated bandwidth allocation algorithm that efficiently assigns the users access to the wireless ATM channel by considering their requested bandwidth and QoS required. Integration of voice, VBR, data, and control traffic over the wireless ATM channel using the proposed DRA-TDMA protocol is considered in this paper. Simulation results are presented to show that the protocol respects the required QoS of each traffic category while providing a highly efficient utilization of approximately 98.33% for the wireless ATM channel. |
