Analysis of packet reservation multiple access: voice data integration for wireless networks

Abstract

It is shown that PRMA (packet-reservation multiple-access) gracefully accepts low-rate data terminals with moderate data packet delays. Due to the two classes of terminals, calculation of system equilibrium requires the solution of two simultaneous nonlinear equations. By a judicious change of variables, this is reduced to a univariate problem of the same form as the speech-only system. Results for a particular design example show that, with a small reduction in the number of speech terminals, all terminals can be provided with a low-rate data capability (1200/2400 b/s) with data packet delays of a few hundred milliseconds. The results are of interest in connection with the development of future microcellular systems which will require distributed network control.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
