Agent technologies for pervasive computing and communications

The structure of the systems underlying a pervasive computing environment is dynamic and continuously changing. Consequently, their architectures must have the ability to react to events and perform architectural changes autonomously. In this paper, our principle is to use our platform based agents to achieve these functionalities, to monitor the global architecture and to evaluate and manage changes in an architecture dynamically at execution time. This platform can support automatic configuration and selection of service coalitions to accomplish computing tasks and reestablish computing contexts. It helps for accomplishing a task and compensating for resource limitations in an environment. The capacity of automatic task-based service discovery and configuration of this platform makes rapid configuration possible, even in the presence of large dynamic collections of devices and resources. In this paper we present the conception and implementation of this platform. A case study is presented showing the application of our platform on client-server architecture and its benefits in the pervasive world are outlined.
