Existing sensor-assisted mHealth applications wouldbenefit from large-scale sharing of sensor information in realtime.Existing communication solutions are however limited inthis respect, because of centralized application-level communication.In response to this, we presents a distributed communicationsolution for mHealth applications which circumvents these limitations.Our Internet-of-Things architecture enables mHealth applicationsto utilize information from sensors and wireless sensornetworks via a peer-to-peer overlay, where sensor information isorganized in an information model which is stored in the overlayitself. We present a proof-of-concept application and evaluationresults regarding the architecture’s real-time capabilities. Theresults indicate that a fully distributed architecture can supportreal-time sensing in mHealth applications and the support isavailable as an open source platform, MediaSense. Current workis focused on evaluating scalability in very large scale scenariosusing field trials.
