The use of wireless networks to support co … The use of wireless networks to support communications with real-time restrictions is becoming a common requirement within environments such as industries, autonomous vehicles, and aerospace technologies, including also the support for cyber-physical systems (CPS). An effective real-time support on the wireless realm is still an open issue, relying on the presence of dependable and fault tolerant communication services, which are built upon fundamental mechanisms such as error detection. In this paper we continue to explore the low levels of the networking protocol stack in the design of a robust foundation to efficiently support real-time on wireless networks; focused on low level error detection, we present the innovative idea to combine error protection mechanisms for enhancing the capabilities and accuracy of a wireless node in the detection of node failures. This paper shows how our low level error detection approach can be utilised to detect and differentiate node transient omission failures, node permanent failures (e.g., in the transmitter circuitry), and node crash failures in wireless communications. crash failures in wireless communications.
