Abstract EN:

Recently, much research has focused on the evolution of the future Internet and the evolution of future services. Toward the target of communication by anyone, anywhere and anytime, the emerging Ambient networks encompass several domains of research, including the mobile computing, distributed systems, ubiquitous computing, pervasive computing and Grid computing. However, the lack of support for mobility and continuity of service results in current monolithic applications no longer being adapted to system of Ambient networks. In this dissertation, we propose a new design composition of service which better matches the needs of Ambient networks, and helps us to provide the application service to adapt to Ambient networks in their heterogeneity and dynamic variability of environment. We analyze the lifecycle management for the service composition process, and give a new design for the layered architecture of Ambient networks, each layer is represented by an overlay network. For the service middleware, we propose our special method to manger distributed services, and divided them into different service groups according to their providing functionalities and their QoS feature. So, services in the same group are found to provide the same function and present the same characteristic of QoS. To support the qualified service groups’ management in the service middleware, our solution relies on the P2P network. In fact, two kinds of P2P protocols, including the modified CAN and Chord, are taken into the implementation phase. Our concept is evaluated by the simulation, and the results demonstrate the advantage and the performance presented in our proposition.
