Gestion de conflits dans une plateforme ubiquitaire orientée services

Abstract : The important emergence of dynamic and heterogeneous devices paves the way for the emergence of a new type of ubiquitous applications that has the ability to interact with sensors and actuators that penetrate our environments in a transparent way. In this research, we are particularly interested in the ubiquitous applications deployed in smart homes. Service-oriented platforms are widely used to run these applications. These platforms present the ability to dynamically provide services, according to the applications needs. These services can be simple, representing a device, or more abstract, providing higher level functions. Ubiquitous applications share these services to achieve different and sometimes conflicting goals. These conflicts need to be managed in order to keep the houses in consistent states. This thesis defines an approach for managing conflicts between home applications in a service-oriented platform. This approach is optimistic and addresses conflicts at runtime via a causal model of the environment, called context. This approach focuses mainly on three axes: the first axis focuses on the description of conflicts in a context modeled as service-oriented components; the second axis consist in the extension of the programming model of ubiquitous applications by locking/unlocking mechanisms; the third axis focuses on conflict management using a three-phase approach (prevention, detection and resolution). The proposed solution was developed as iPOJO components and integrated into the ubiquitous platform iCasa.
