Computing and Informatics

SAPERE (``Self-Aware Pervasive Service Ecosystems'') is a general framework to support the decentralized execution of self-organizing pervasive computing services. In this paper we present the rationale underlying SAPERE and its reference conceptual architecture. Following, we sketch the middleware infrastructure of SAPERE and detail the interaction model implemented by it, based on a limited set of ``eco-laws'' allowing general-purpose distributed self-organizing schemes. Finally, we show how a social application can be easily implemented exploiting such an infrastructure and report on performances.
