Self-organisation is a promising solution for building complicated, large-scale software systems that must meet stringent adaptability and survivability requirements. At the same time, controlling self-organising software to ensure global system properties and functions is a difficult problem. This paper proposes a solution that uses architectural templates, or archetypes, replicated across a set of identical agents, and interpreted at runtime to control the agents' self-organising behaviour and results. The solution ensures, by construction, that any resulting software system meets a set of predefined goals, or constraints, while maintaining many of the self-organisation related advantages. A framework prototype was implemented and tested to show the viability of the proposed approach, in the context of a distributed data-mediation application.

International audienceIn this paper we present a modular, flexible and extensible RFID middleware architecture. The functionalities needed by an RFID middleware are already well studied, also there exists some standards which define them. We propose an architecture where these functionalities are developed in an event-oriented component model. This provides extra benefits such as loose coupling between components and an easy-to-scale architecture
