Near-optimal voice-data integration over third generation medium and high capacity wireless TDMA channels

A new multiple access control (MAC) protocol for mobile wireless communications is presented and investigated. We explore, via an extensive simulation study, the performance of the protocol when integrating voice and data traffic over two wireless channels, one of medium capacity (referring mostly to outdoor microcellular environments) and one of high capacity (referring to an indoor microcellular environment). We evaluate the voice packet dropping probability and access delay, as well as the data packet access and data message transmission delays for various voice and data load conditions. Our protocol achieves near-optimal voice sources multiplexing results along with most satisfactory voice and data performance and quality of service (QoS) requirements servicing.
