Lessons learned implementing the ISO/IEEE11073 standard into wearable personal devices

In this paper several approaches to implement the ISO/IEEE11073 interoperability standard into personal health devices using low-voltage low-power (LV-LP) microcontrollers are proposed. The patterns methodology previously suggested by the authors is followed in all of the approaches which include an 1-process implementation using non-blocking functions, multiprocess within an operating system, an specific multithread framework, and a code compression based interpreter. Finally, a qualitative comparison between the different approaches is provided.
