Abstract:

An Automatic Repeat Request (ARQ) scheme is proposed for a wireless ATM LAN based on the MEDIAN concept. Simulations have been performed to demonstrate the consequences of ARQ inclusion in terms of required buffer capacity and resulting cell end-to-end delay. In particular, the behaviour of the ARQ-enhanced system for real-time traffic under non error-free conditions has been examined. The main result of the simulations is that, due to specific properties of the MEDIAN wireless ATM LAN, the proposed ARQ scheme is suitable for real-time ATM services, while yielding virtually error-free links. Next to low cell delay, it features low overhead and low processing complexity whereas it can be readily combined with a simple and efficient MAC scheme.
