Introducing contextual objects in an adaptive framework for wide-area mobile computing
Anne-Marie Kermarrec, Paul Couderc, Michel Banâtre · 1998
The emergence of mobile computing combined with the increasing popularity of the Internet has introduced new challenges that are not addressed in traditional distributed systems.In particular, mobile computing is characterized by the extreme variability of the environment components such as network bandwidth, computing power, location, services available, etc.The goal of our work is to provide a framework to dynamically adapt applications to the continuous changes of mobile environments including physical constraints and more qualitative changes.As a basis of our work, we present in this paper the concept of contextual objects.This approach allows to express the dependencies of an object according to a number of contexts such as the time, the location or the physical aspects (available network bandwidth or computing power) in a changing environment.
