Management of Context in Mobile Environments

摘要

Mobility becomes a mode of life or work, ubiquitous access to information becomes necessary. At the same time, technological advances in wireless networks and the success of handheld computers and mobile phones are encouraging this movement. The diversity of modes of interaction in mobile environments must allow users to access information anywhere and at any time. This flexibility makes users more demanding and brings new challenges to user interfaces. For this, the context must be well understood and managed in an appropriate form to promote sharing between the different devices and offer a high level of abstraction. Several architectures have been developed to allow context management in mobile environments. To face the challenges of context management in mobile environments, and taking into account the limits of existing solutions, we offer a modular and flexible architecture, which takes the context as the most important element to reason, adapt and provide a service in a appropriate form.
