Abstract The purpose of this paper is to present an edge pervasive platform supporting the development, deployment and management of flexible, context-aware pervasive applications. This platform, named iCasa, is built on top of the OSGi/iPOJO serviceoriented component model. It includes an autonomic context module connected to the physical environment and providing information as a dynamic set of services. This context is dynamic in order to reflect the changing nature of the execution environment but also to deal with applications evolving needs. ICasa also comes with an Eclipse-base development environment including a source code editor, build automation tools, automated deployment facilities, and a smart home configurator and simulator. ICasa has been validated on a variety of applications, mostly in collaboration with Orange Telecom company and Schneider Electric. It is available on the Internet (self-star.net) and is heavily used today for teaching purposes, in addition to industrial developments.

1 Introduction Pervasive computing (Weiser 1995; Satyanarayanan 1996) promotes the integration of electronic devices in our living spaces in order to assist us in our daily activities, be they professional or private. These pervasive devices can be blended in the environment, integrated in smartphones or even woven into clothing. They are mobile or static, can take multiple forms, and pick up a wide variety of signals in the environment. Pervasive devices collect contextual information, run local computation, and, in some cases, direclty act upon the environment. This allows the implementation of simple, reactive services like opening an emergency door when a triggering condition is detected. Pervasive devices are also enhanced with networking capabilities so that they can communicate with each other or with more powerful computing elements, located in close proximity or in the cloud. This is of course necessary to implement more

complex services, based on various data sources and requiring significant computing and memory capacities. The proliferation of such pervasive devices, coupled with the widespread availability of the Internet, makes pervasive computing more concrete every day. Whether at home, in commute, or at work, we can already enjoy a variety of simple, unobtrusive services enhancing quality of life or optimizing resources management. These services are however still limited in terms of performance, security, cost and even added value. Clearly, much progress is still needed to
