A Study of Channel-Access Schemes for Integrated Voice/Data Radio Networks

Abstract

In this report we address the major issues associated with channel access in integrated wireless networks, and we propose and analyze the Pure- Reservation Voice/Data Non-Interleaved-Frame Fixed-Length (PR-VD-NIFFL) protocol. This scheme is well suited to either satellite or to terrestrial networks. A two-dimensional first-order Markov chain model for this scheme is presented, and techniques that exploit the structural properties of this chain to simplify the evaluation of the equilibrium state, without sacrificing accuracy, are described. Analytical models for the evaluation of data-packet delay for both fixed- and movable-boundary versions' of this protocol and for voice-call blocking probability are presented. Computational results illustrate the dependence of performance on system parameters and demonstrate the improvement that can be achieved through the use of the movable-boundary version.
