“…Dimopoulos et al [12] consider mixed criticality systems, speci cally for smart building infrastructure. One interesting aspect they mention is the potential use of SDRs (software de ned radios) in the implementation of CPS, in order to present more adaptability in the behaviour and protocols employed.…”

“…Other works [25,37] require speci c radio hardware support, in the form of channel clear assessment or listening detection in particular slots. Compared to the units evaluated in [12], AirTight does not require software de ned radios and is capable of functioning upon commodity devices with xed radio transceivers. Xia et al [41] does not incorporate mode changes so cannot free up additional processing to handle the fault situation by stopping LO transmissions; [40] considers schedulability parameters but does not consider the impact of long-lasting temporal faults.…”

This paper describes the motivation, design, analysis and con guration of the criticality-aware multi-hop wireless communication protocol AirTight. Wireless communication has become a crucial part of the infrastructure of many cyber-physical applications. Many of these applications are real-time and also mixed-criticality, in that they have components/subsystems with di erent consequences of failure. Wireless communication is inevitably subject to levels of external interference. In this paper we represent this interference using a criticality-aware fault model; for each level of temporal interference in the fault model we guarantee the timing behaviour of the protocol (i.e. we guarantee that packet deadlines are satis ed for certain levels of criticality). Although a new protocol, AirTight is built upon existing standards such as IEEE 802.15.4. A prototype implementation and protocol-accurate simulator have been produced. This paper develops a series of schedulability analysis techniques for single-channel and multichannel wireless Cyber-Physical Systems (CPS). Heuristics are speci ed and evaluated as the starting point of design space exploration. Genetic algorithms are then de ned and evaluated to assess their performance in developing schedule tables incorporating multichannel allocations in these systems. CCS Concepts: • Computer systems organization → Embedded and cyber-physical systems; Realtime systems; • Software and its engineering → Software veri cation;

A Survey of Research into Mixed Criticality Systems

2017

This survey covers research into mixed criticality systems that has been published since Vestal's seminal paper in 2007, up until the end of 2016. The survey is organised along the lines of the major research areas within this topic. These include single processor analysis (including fixed priority and EDF scheduling, shared resources and static and synchronous scheduling), multiprocessor analysis, realistic models, and systems issues. The survey also explores the relationship between research into mixed criticality systems and other topics such as hard and soft time constraints, fault tolerant scheduling, hierarchical scheduling, cyber physical systems, probabilistic real-time systems, and industrial safety standards. CCS Concepts: •Computer systems organization → Real-time system specification; •Software and its engineering → Real-time schedulability; Real-time systems software;

This paper describes the motivation, design, analysis and implementation of a new protocol for critical wireless communication called AirTight. Wireless communication has become a crucial part of the infrastructure of many cyber-physical applications. Many of these applications are real-time and also mixed-criticality, in that they have components/subsystems with different consequences of failure. Wireless communication is inevitably subject to levels of external interference. In this paper we represent this interference using a criticality-aware fault model; for each level of interference in the fault model we guarantee the timing behaviour of the protocol (i.e. we guarantee that packet deadlines are satisfied for certainly levels of criticality). Although a new protocol, AirTight is built upon existing standards such as IEEE 802.15.4. A prototype implementation and protocol-accurate simulator, which are also built upon existing technologies, demonstrate the effectiveness and functionality of the protocol.
