“…The base station has absolute control in determining the number of each type of slots during TABLE I DR-TDMA MAC FRAME PARAMETERS a frame period and which mobile stations will receive or send information using the data slots. System parameters adopted for the DR-TDMA protocol are according to the literature [2], [9] and are summarized in Table I. It should be noted that the only parameters that directly influence the MAC protocol efficiency are: the frame duration, the number of control and data slots per frame, and the ratio of data slot size to control slot size.…”

“…Another useful performance measure introduced in [9] is the allocation efficiency (AE) defined as the fraction of slots allocated to VBR traffic that are actually used for transmissions. A high AE index indicates a good match between the virtual status at the base station scheduler and the real status of the respective mobile station.…”

“…In this paper, we use a novel predictive approach where the base station estimates from a limited number of parameters the current requirements of the connections. A similar predictive approach has been proposed in [9] for VBR traffic. However, with the method that we are proposing in this paper, by forcing the VBR source to be rate-controlled, we are able to significantly increase the performance.…”

“…Another area where most of the previously proposed protocols present some pitfalls is related to the random access protocols employed for initial access. They either limit the delay-throughput performance [5], [8], [9] or restrict the number of users [10]. Generally they do not offer access priorities between different service classes.…”

Abstract-A dynamic reservation time division multiple access (DR-TDMA) control protocol that extends the capabilities of asynchronous transfer mode (ATM) networks over the wireless channel is proposed in this paper. DR-TDMA combines the advantages of distributed access and centralized control for transporting constant bit rate (CBR), variable bit rate (VBR), and available bit rate (ABR) traffic efficiently over a wireless channel. The contention slots access for reservation requests is governed by the framed pseudo-Bayesian priority (FPBP) Aloha protocol that provides different access priorities to the control packets in order to improve the quality-of-service (QoS) offered to time sensitive connections. DR-TDMA also features a novel integrated resource allocation algorithm that efficiently schedules terminals' reserved access to the wireless ATM channel by considering their requested bandwidth and QoS. Integration of CBR, voice, VBR, data, and control traffic over the wireless ATM channel using the proposed DR-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 96% for the wireless ATM channel.

SUMMARYThe token bank fair queuing algorithm (TBFQ) is a novel scheduling algorithm that is suitable for wireless multimedia services. The bandwidth allocation mechanism integrates the leaky bucket structure with priority handling to address the problem of providing quality-of-service (QoS) guarantees to heterogeneous applications in the next generation packet-switched wireless networks. Scheduling algorithms are often tightly integrated with the wireless medium access control (MAC) protocol. However, when heterogeneous wireless systems need to be integrated and interoperate with each other, it is desirable from the QoS provisioning standpoint to decouple scheduling algorithm from the MAC protocol. In this paper we propose a framework of seamless QoS provisioning and the application of TBFQ for uplink and downlink scheduling in wireless networks. We study its performance under a generic medium access framework that enables the algorithm to be generalized to provide QoS guarantees under various medium access schemes. We give a brief analysis of the algorithm and compare its performance with common scheduling algorithms through simulation. Our results demonstrate that TBFQ significantly increases wireless channel utilization while maintaining the same QoS, unlike many fair queuing algorithms, TBFQ does not require timestamping information of each packet arrival}an impractical feature in an already resource scarce environment. This makes TBFQ suitable for wireless multimedia communication.
