A framework for dynamic adaptation in wireless environments

Abstract

The important differences between wireless and wired environments make it indispensable for applications to adapt to the type of environment in which they execute. Solutions provided by existing approaches are often embedded in the heart of the applications functionalities making them more difficult to develop and to maintain. We propose the utilization of an adaptive framework, MoleNE, which provides applications with a set of services as an abstraction of concepts usually utilized to manage mobility issues. Services are built as a set of MoleNE components that can be customized for different applications. Further a MoleNE component can be provided with a special object the Controller, which performs the adaptation of the component behavior depending on the execution conditions. This paper describes the architecture of MoleNE components and gives evidence of the easy use of the adaptation mechanisms by presenting an adaptation strategy for a transactional hospital application.
