Automatic resource and service management for ubiquitous computing environments

The high degree of dynamism and heterogeneity of the resources involved in a pervasive computing environment makes service adaptation and interoperability a difficult task. We present UBIDEV, a service framework that faces the heterogeneity problem by hiding at the application level the dynamism of the underlying environment. We describe the UBIDEV architecture focusing on the description and the management of services and resources. We also describe how this approach decreases the complexity of the design and development of service-oriented applications. A prototype implementation of a unified messaging system is presented as a validation of the architectural design.
