Towards Self-evolving Context-aware Services

Abstract

The introduction of new communication infrastructures such as Beyond 3rd Generation
(B3G) and the widespread usage of small computing devices are rapidly
changing the way we use and interact with technology to perform everyday tasks.
Ubiquitous networking empowered by B3G networking makes it possible for mobile
users to access networked software services across continuously changing heterogeneous
infrastructures by resource-constrained devices. Heterogeneity and devices'
limitedness, create serious problems for the development and dynamic deployment
of mobile applications that are able to run properly on the execution context and
consume services matching with the users' expectations. Furthermore, the everchanging
B3G environment calls for applications that self-evolve according to context
changes. Out of these problems, self-evolving adaptable applications are increasingly
emerging in the software community. In this paper we describe how
CHAMELEON, a declarative framework for tailoring adaptable applications, is being
used for tackling adaptation and self-evolution within the IST PLASTIC project.
