Abstract
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.
