Abstract

This paper presents a performance analysis of a random access (RA) protocol that is in use in a TDMA wireless multi-access channel. The channel is shared in mixed voice and data with general distribution. The work considers a class of data that consists of a finite number of open sessions. Users contend in uplink using an RA protocol based on S-Aloha and contention takes places every N c frames. We start with a general model description of a voice and data subsystem in which admission protocols are explained. An analytical framework is derived. An algorithm is then formulated that complements the analytical framework The analysis is based on Equilibrium-Point-Analysis (EPA) and is novel and topical. Numerical results are corroborated using a simulation in OPNET.
