Abstract

In this paper we analyze the problem of designing the medium access control (MAC) module under quality of service (QoS) constraints for real-time services. The attention is focused on the case of slowly time-varying channels, such as in wireless local area networks (WLAN), and an analytical approach for the optimization of transmission efficiency is presented. In the paper we also propose a novel automatic repeat on request (ARQ) protocol which allows reduction of protective overhead for each transmitted data unit, resulting in a minimum increase of reserved bandwidth.
