Adaptive Service-Oriented Mobile Applications: A Declarative Approach

Modern society increasingly relies on mobile devices and on distributed applications that use them. To increase development efficiency and shorten time-to-market, mobile applications are typically developed by composing together ad-hoc developed components, services available on-line, and other third-party mobile applications. To cope with unpredictable changes and failures, but also with the various settings offered by the plethora of devices, mobile applications need to be adaptive. We address this issue by proposing a declarative approach. The advantages of the proposed solution are demonstrated through an example inspired by an existing worldwide distributed mobile application.
