Adopting a middleware for self-adaptation in the development of a smart travel system

A smart travel system is a complex distributed system acting as a tour operator for organizing holiday packages and supporting travelers on-the-run. A couple of key characteristics of such a system are the ability of self-configuring a set of heterogeneous services and self-adapting to unexpected circumstances. This paper reports an experience of developing a smart travel system by adopting MUSA, a Middleware for User-driven Service Adaptation. The prototype supports users in organizing their time by the specification of goals: this triggers the automatic composition and dynamic orchestration of touristic services. The chosen middleware has played a fundamental role by simplifying the development process thus to speed up the time-to-complete.
