Abstract :
Due to several advantages, such as flexibility, increased mobility, and lower costs, the deployment of wireless technologies in factory automation systems is rapidly growing. However, current wireless technologies, e. g., IEEE802.11 Wireless Local Area Networks (WLANs), are not able to satisfy the requirements of industrial applications in terms of real-time communication. In this paper medium access control mechanisms in IEEE 802.11 are investigated and a new isochronous MAC is proposed. In combination with a traffic scheduler specifically designed for it, typical constraints of soft real-time flows found on the factory floor can be satisfied. A preliminary analysis shows the effectiveness of the proposed combination.
