The World Wide Web is becoming increasingly personalized as users provide more of their information on the Web. Thus, Web service functionality is becoming reliant on user profile information and context in order to provide user-specific data. In this paper, we discuss enhancements to SECE (Sense Everything, Control Everything), a platform for context-aware(More)
The <i>SECE</i> (Sense Everything, Control Everything) system allows users to create services that combine communication, calendaring, location and devices in the physical world. <i>SECE</i> is an event-driven system that uses a natural-English-like language to trigger action scripts. Presence updates, incoming calls, email, calendar and time events, sensor(More)
Sense Everything, Control Everything (SECE) is an event-driven system that lets nontechnical users create services that combine communication, location, social networks, presence, calendaring, and physical devices such as sensors and actuators. SECE combines information from multiple sources to personalize services and adapt them to changes in the user's(More)
Traditionally, cellular wide area networks like UMTS are used as Internet access networks for particular users but, in some cases, they can be employed to provide Internet access to other smaller networks as well. The main inconvenient is that cellular networks have not the same bandwidth than wired networks and therefore, the cellular channel becomes a(More)
The WebRTC technology is gaining more and more attention in the Telco world. After having detailed this technology and its stakes, we remind in this paper some limits of the current architectures for conversational services, and we expose how webRTC could be used by Telcos. Two scenarios are possible: Extending the IMS footprint and introducing a new(More)
Secured interpersonal communications should come with asserted user identities and trust between the involved parties. No single trust model exists in Web Real-Time Communications services, so neither is there a single identity architecture. The authors discuss different models for provisioning user identity and their impact on user privacy.
The Social Internet of Things (SIoT) is aimed at integrating devices into users' daily life by taking advantage of the interconnectivity and user-friendliness of Social Networks (SNs). To ensure the success of SIoT, we need to provide new attractive services that engage people to socialize their devices. Automation is a requirement to seamlessly integrate(More)
Cellular wide area networks like UMTS can be employed to provide Internet access to other smaller networks. The main inconvenient is that cellular networks have not the same bandwidth than wired networks and therefore, the cellular channel becomes a network bottle-neck. To help to mitigate this situation different optimization techniques exist, especially(More)
