Abstract: In recent years, many researchers have studied context-awareness to support non-intrusive adaptability
of context-aware applications. Context-aware applications benefit from emerging technology that connects
everyday objects and provides opportunities to collect and use context information from various
sources. Context-awareness helps to adapt continuously to new situations and to turn a static computing
environment into a dynamic ecology of smart and proactive applications. In this chapter, we present
our framework that manages and uses context information to adapt applications and the content they
provide. We show how application adaptation can be handled at the composition level, by reconfiguring,
redeploying and rewiring components, e.g. to fall back into reduced functionality mode when redeploying
an application on a handheld. The key features of our context-aware adaptation framework not only include local adaptations of context-aware
applications and content, but also the addressing
of context in large scale networks and the contextaware
redeployment of running applications in a
distributed setting. We discuss how adaptation is
handled along various levels of abstraction (user,
content, application, middleware, network) and
illustrate the flexibility of context-aware content
and application adaptation by means of a realistic
use case scenario.
