Towards a Chemical-Inspired Infrastructure for Self-* Pervasive Applications

Abstract

Stimulated by the increasing availability of new mobile computing devices and the corresponding demand of open, long-lasting, and self-organising service applications, recent works proposed the adoption of a nature-inspired approach of chemistry for implementing service architectures 33. One work in this direction is the chemical tuple-space model 30, by which the existence of data, devices and software agents (in one word, services of the pervasive computing application) gets reified into proper tuples managed by the infrastructure. System behaviour is accordingly expressed by chemical-like reactions that semantically match those tuples and accordingly enact the desired interaction patterns (composition, aggregation, competition, contextualisation, diffusion and decay). After motivating the proposed approach for situated, adaptive, and diversity-accommodating pervasive computing systems, in this paper we outline an incarnation of this model based on the TuCSoN coordination infrastructure, which can been suitably enhanced with modules supporting semantic coordination and execution engine for chemical-inspired coordination laws.
