Abstract

Current wireless multimedia applications may require different quality-of-service (QoS) measures such as throughput, packet loss rate, delay, and delay jitter. In this paper, we propose an access scheme for CDMA networks that can provide absolute QoS guarantees for different service classes. The access scheme uses several M/D/1 queues, each representing a different service class, and allocates a transmission rate to each queue so as to satisfy the different QoS requirements. Operation in error-prone channels is enabled by a mechanism that compensates sessions, which experience poor channels. Analysis and simulation results are used to illustrate the viability of the access scheme.
