Abstract : Ubiquitous systems have to cope with more heterogeneous and more dynamic environments than traditional distributed systems. The criticity of application domains related to ubiquitous computing requires to ensure the robustness of applications before their deployment in actual situations. Some approaches handle the dynamicity of ubiquitous environments but propose generic programming frameworks. This genericity is a major obstacle for producing robust applications. Other approaches enable more verifications that ensure, for example, communication integrity. However, as performed by these approaches, these verifications are not compatible with managing constant changes of ubiquitous environments. This thesis proposes a declarative approach to generate software frameworks for ubiquitous computing. Our approach relies on high-level specifications of target applications. These specifications, written in the DIASPEC language, are analyzed, checked and compiled by the DIASPEC compiler which generates dedicated software frameworks, including programming frameworks and simulation frameworks. The generated programming frameworks provide programming support for developing ubiquitous applications while the generated simulation frameworks provide testing support for these applications. Programming frameworks ensure communication integrity while handling the dynamicity of ubiquitous environments. Furthermore, they are generated on top of a generic middleware; the layered architecture of this middleware allows ubiquitous applications to be independent of underlying technologies. The contributions of this thesis are as follows:
• We present the DIAGEN approach which proposes to generate, from specifications of ubiquitous software architectures, programming support and verifications dedicated to the development of ubiquitous applications. These specifications are written in a declarative language, called DIASPEC, which allows to describe all service types composing the target ubiquitous applications. The DIASPEC compiler checks the specification consistency and generates dedicated programming frameworks. These programming frameworks ensure communication integrity of dynamic applications. The underlying middleware has a layered architecture, making programming frameworks independent of software buses. Thus, applications are portable without modification.
• We present the DIASIM simulator that tests, at run time, the behavior of applications developed with DIAGEN. DIASIM allows to test applications without modification and to incrementally integrate actual services in simulation scenarios.
• We show that DIAGEN applications are more concise than existing approaches while enabling more verifications and handling the dynamicity of ubiquitous environments.
