Wireless networks are typically deemed not reliable enough to address real-time requirements typical of industrial distributed control applications. Several solutions were proposed in the past years to overcome their limitations and make them suitable for those (soft) real-time applications where a limited percentage of deadlines can be missed. A promising approach relies on centralized transmission...
Seamless redundancy can be profitably exploited to improve predictability of wireless networks, including IEEE 802.11. Packets are sent on two channels at the same time and duplicate copies are discarded by receivers. As long as behavior of channels is reasonably uncorrelated, both transmission latencies and the frame loss ratio improve noticeably. In this paper, such an assumption has been analyzed...
Nowadays, industrial control networks are no longer conceived as isolated systems, being them exposed to the same kind of security threats affecting traditional office and business networks. For this kind of systems, the main security requirement is availability, thus the protection measures used to secure industrial control networks must take into account also performance aspects, such as latency...
The ability to carry out coordered activities in distributed applications is currently considered a basic requirement in most industrial scenarios as well as in many areas with demanding real-time constraints, such as modern electric power systems, the automotive/avionic domains, and some types of networked embedded control systems. For this reason, the majority of the networks that were conceived...
