Wireless Mesh Networks propose a decentralized architecture for establishing multi-hop wireless communications. The decentralized architecture brings benefits such as ease of deployment and maintenance, scalability and reliability. However, wireless mesh networks lack high level services such as handoff and mobility management or admission control. OpenFlow(More)
The 3GPP has specified the IP multimedia subsystem (IMS) for the provisioning of multimedia services in UMTS Release 5 and later. Interconnection at the service layer between 3GPP and LAN networks requires interworking between IMS and WLAN functionalities. Studying several interconnection scenarios and the main functionalities of IMS, this article analyzes(More)
Isabel is a P2P like multipoint group collaboration tool for the Internet, which implements an innovative service concept for synchronous collaborations based on a flexible and programmable floor control. This approach leads to a more natural and effective management of collaboration sessions. The flexible and programmable floor control incorporates the(More)
Introduction Many activities which in the past have required physical presence and direct interaction among participants can be performed in a distributed fashion with the help of advanced information technologies such as, CSCW [1,2] (Computer Supported Cooperative Work), interactive multimedia services and broadband communications. Technologies aiming at(More)
Results of the conceptual work carried out during the BRAIN project concerning the BRAIN QoS Framework and the Brain ENd Terminal Architecture (BRENTA) is presented. This includes mechanisms to specify and manage QoS End-to-End including mobile end-systems and IP based wireless access networks in the transmission path. One of the key points is to manage QoS(More)
Many different open information sources currently exist for protecting the environment in Europe, mainly focused on Natura 2000 network, and areas where environmental protection and activities like tourism need to be balanced. Managing these data and integrating them for supporting decision makers and for novel uses is a challenging task. The SmartOpenData(More)
Nowadays, manufacturing processes have become highly complex. Besides, more and more, governmental institutions require companies to implement systems to trace a product's life (especially for foods, clinical materials or similar items). In this paper, we propose a new framework, based on cyber-physical systems, for developing traceability systems in small(More)
