Time-Frequency Slicing with Distributed-Queueing Request Update Multiple Access (DQRUMA) for Multi-Rate Wireless Packet (ATM) Networks

Abstract

In a wireless packet (ATM) network that supports an integrated mix of multimedia traffic, a large variety of mobiles with different service rates will need to be accommodated efficiently in a unified bandwidth-on-demand fair-sharing manner. In this paper, we propose and study a Time-Frequency Slicing with Distributed-Queueing Request Update Multiple Access (DQRUMA) protocol for wireless packet (ATM) networks that support mixes of multi-rate traffics. The protocol incorporates Time-Frequency Slicing (an efficient multiplexing scheme for providing multi-rate packet transmissions) and DQRUMA (an efficient demand-assignment multiple access protocol for wireless access and scheduling) to form a unified bandwidth-on-demand platform for multi-rate wireless services. A slot-by-slot packet transmit scheduling policy named Bandwidth-on-Demand Fair-Sharing Round-Robin (BoD-FSRR) shares the system bandwidth amongst different rate classes of mobiles according to their demand on a fair-sharing basis. Simulation results show that the system provides close to ideal access performance for different rate classes of mobiles.KeywordsTime SlotPacket TransmissionRate ClassRate MobileCall HandoffThese keywords were added by machine and not by the authors.
