A Self-Organising Infrastructure for Chemical-Semantic Coordination: Experiments in TuCSoN

Recent works proposed the adoption of a nature-inspired approach of chemistry for implementing service architectures suitable for pervasive applications. In particular, Viroli and Casadei propose a chemical-semantic tuple-space model where coordination of data, devices and software agents — representing the services of the pervasive computing application — are reified into proper tuples managed by the coordination infrastructure. Service coordination is enacted by chemical-like reactions that semantically match those tuples accordingly enacting the desired interaction patterns (composition, aggregation, competition, con- textualisation, diffusion and decay). After showing and motivating the proposed coordination approach for situated, adaptive, and diversity-accomodating pervasive computing systems, in this paper we outline how it is possible to concretise the approach on the TuCSoN coordination infrastructure, which can been suitably enhanced with modules supporting fuzzy semantic-coordination and execution engine for chemical-inspired coordination laws.
