Decision Management and Object-oriented Protocol and Services Reconfiguration in Future Internet Autonomic and Heterogeneous Telecommunication Environments

In recent years, the vast evolution in telecommunication systems is remarkable, as regards the fast development and incorporation of new technologies in the heterogeneous networking environment. One major issue concerns the complexity management in user connectivity, in relation with two fundamental alternative solutions: the development of interworking functions for handovers between heterogeneous systems and the introduction of mechanisms for dynamic adaptation and reconfiguration. This phd thesis focuses on the second solution, which is called to overcome the design limitations of the first one. Specifically, the addressed issues concern the introduction and impact of reconfiguration in local (per device) and network levels, for the component-based dynamic adaptation of mobile devices and network elements. In the context of this thesis, special emphasis is paid on the specification and the detailed design of the reconfiguration deployment in the protocol stack and the service level, using object-oriented models. In addition, the mechanisms’ evaluation and assessment was realized locally in the mobile devices, as regards the possibility of their deployment and the feasibility of the approach. Special focus was paid on the global evaluation and assessment of the introduced mechanisms for protocol reconfiguration in the heterogeneous network environment, taking into account different types of mobile devices with varying capabilities: reconfigurable and autonomous mobile devices.
