Abstract : The pervasive computing vision introduced by Mark Weiser in the early 90-s, results from the convergence of powerful, small, affordable computing devices with networking technologies that tie them all together. Still, the development of software systems for pervasive computing environments requires dealing with numerous challenges that are primarily due to the dynamics, mobility and heterogeneity inherent to these environments. Middleware technologies that deal with the dynamics and homogenize the diversity of technologies appear as a major enabler for the development of pervasive computing software systems. Further, service-oriented middleware SOM where functional and non- functional capabilities provided by pervasive networked resources are abstracted as services appear to be the most appropriate for pervasive computing environments. However, the dynamic discovery and composition of networked services by applications, which constitute two of the main functionalities of a SOM, require service requesters and providers to agree on both the functional and non-functional semantics of service capabilities. This, cannot be achieved on a syntactic basis in open pervasive computing environments. A promising approach then, relies on the semantic modelling of services functional and non-functional capabilities. In the above direction, this thesis introduces a semantic, service-oriented middleware for pervasive computing. The most significant contributions are: 1 an extensible semantic service model and its associated conformance relations; 2 an efficient semantic service registry for highly interactive pervasive environments; and 3 the support for adaptive QoS-aware service composition that allows taking full advantage of the diverse capabilities of each pervasive environment.
