This paper describes the design and implementation of a high-reliability and low-power status monitoring protocol, e.g. for wireless alarm systems. The dual design approach followed consists of an in-depth device characterization with subsequent algorithm development. This allows to understand and leverage the correct design and implementation of the most critical components of the algorithms. The high-reliability status monitoring protocol operates based on monitoring windows with synchronous notification, subsequent acknowledgement rounds and periods of reduced activity, at regular intervals. This leads to deterministic and thus highly reliable operation of the status monitoring protocol implementation on the Tmote Sky platform.
