Traffic scheduling in wireless ATM networks

Abstract

Wireless ATM is enjoying enormous research interest in the last few years, because of its ability to combine multimedia applications support, together with the freedom of mobility. One of the key design issues is the medium access control (MAC) protocol for the radio interface. This paper presents the traffic scheduling algorithm used in the MAC protocol of the Wireless ATM Network Demonstrator (WAND) system being developed within project Magic WAND. Magic WAND is investigating wireless ATM technology for customer premises networks in the framework of the Advanced Communications Technologies and Services (ACTS) programme, funded by the European Union. The proposed algorithm is delay oriented to meet the requirements of the various traffic classes defined by the ATM architecture. Simulation results are presented to assess the performance of the algorithm.
