4Sensing -- Decentralized Processing for Participatory Sensing Data

Participatory Sensing is an emerging application paradigm that leverages the growing ubiquity of sensor-capable smart phones to allow communities carry out wide-area sensing tasks, as a side-effect of people´s everyday lives and movements. This paper proposes a decentralized infrastructure for supporting Participatory Sensing applications. It describes an architecture and a domain specific programming language for modeling, prototyping and developing the distributed processing of participatory sensing data with the goal of allowing faster and easier development of these applications. Moreover, a case-study application is also presented as the basis for an experimental evaluation.
