This Chapter aims to provide a broad overview on the current results regarding the IEEE 802.11e protocol in industrial communication, with a special focus on the support provided to real-time traffic in factory automation. While Section 2 presents a summary of the IEEE 802.11e protocol, Sections 3 and 4 give an overview of analytic performance models and of the most relevant admission control algorithms currently in literature, respectively. In Section 5 some improved scheduling algorithms for HCCA are presented. In addition, as analytic models prove that the EDCA performance strongly depends on the protocol parameters, some mechanisms that control those parameters to improve the performance of the EDCA traffic will be discussed as well. Section 6 discusses several case studies of using 802.11e for factory automation.

Abstract
This Chapter aims to provide a broad overview on the current results regarding the IEEE 802.11e protocol in industrial communication, with a special focus on the support provided to real-time traffic in factory automation. While Section 2 presents a summary of the IEEE 802.11e protocol, Sections 3 and 4 give an overview of analytic performance models and of the most relevant admission control algorithms currently in literature, respectively. In Section 5 some improved scheduling algorithms for HCCA are presented. In addition, as analytic models prove that the EDCA performance strongly depends on the protocol parameters, some mechanisms that control those parameters to improve the performance of the EDCA traffic will be discussed as well. Section 6 discusses several case studies of using 802.11e for factory automation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
