Technology evolution is providing new pervasive service scenarios characterised by a huge number of distributed and dynamic devices. Accordingly, a new generation of services and infrastructures are emerging which support situatedness, adaptivity and diversity. In this paper we model the overall world of services, data and devices, as a distributed computational ecosystem. As such, each entity will be modelled as an autonomous, spatially-situated individual of the ecosystem, whose existence and state is reified by an LSA (Live Semantic Annotation). Ecosystem behaviour is controlled by coordination rules called eco-laws, which are chemical-like reactions evolving the population of LSAs—similarly to the approaches in [1], [2]. We describe an architecture that is at the basis of the SAPERE project (“Self-aware Pervasive Service Ecosystems”, www.sapere-project.eu), supporting the vision along with a model of eco-laws, and show their usefulness in a scenario of adaptive pervasive displays.

Abstract
Technology evolution is providing new pervasive service scenarios characterised by a huge number of distributed and dynamic devices. Accordingly, a new generation of services and infrastructures are emerging which support situatedness, adaptivity and diversity. In this paper we model the overall world of services, data and devices, as a distributed computational ecosystem. As such, each entity will be modelled as an autonomous, spatially-situated individual of the ecosystem, whose existence and state is reified by an LSA (Live Semantic Annotation). Ecosystem behaviour is controlled by coordination rules called eco-laws, which are chemical-like reactions evolving the population of LSAs—similarly to the approaches in [1], [2]. We describe an architecture that is at the basis of the SAPERE project (“Self-aware Pervasive Service Ecosystems”, www.sapere-project.eu), supporting the vision along with a model of eco-laws, and show their usefulness in a scenario of adaptive pervasive displays.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
