iDSRT: Integrated Dynamic Soft Real-time Architecture for Critical Infrastructure Data Delivery over WLAN

Critical Infrastructures (CIs) such as the Power Grid play an important role in our lives. Of all important aspects of CIs, real-time data delivery is the most important one because appropriate decisions cannot be made without having data delivered in a timely manner. Also, the current trend for the real-time data delivery system, specifically SCADA (Supervisory Control and Data Acquisition) systems, is to move from a closed system toward an open system that has an open architecture and uses mature computer and communication technologies. Specifically, CIs tend to adopt micro-processor-based devices a.k.a. Intelligent Electronic Devices (IEDs) with commodity multi-threaded operating systems such as Linuxbased OSs and COTS wireless LAN technology such as 802.11 WLAN. However, these trends pose a question of whether real-time guarantees, using these technologies, are feasible and can be practically implemented without many modifications of the commodity platform. In this paper, we pre...
