Ubiquitous and pervasive computing is one of the imperatives for the success of mobile communications. In a recent work, we presented WiSwitch, which is a solution for providing, whenever possible, always-on, continuous and optimized network services to mobile users, independently from the underlying technology. Recent studies have shown that mobile users(More)
Traditionally, global node mobility problem is addressed at networking layer (e.g. Mobile IP and related solutions). However, none of these classes of solution is designed for supporting seamless handover switch between different network providers and technologies, where the node accesses the network from another point of access (with new access procedure)(More)
We present a technique for detecting floor changes in an indoor environment and improving pedestrian indoor localization and navigation. Our technique relies on barometric pressure sensors commonly available on smartphones and tablets. We developed an algorithm running on smart mobile devices that can be integrated in any indoor localization system to(More)
OBJECTIVE Fine mapping of HIV-1 gp41 fusion-critical sites. DESIGN AND METHODS Antibodies from human HIV-1-positive sera were affinity-purified on a panel of synthetic overlapping peptides spanning residues 526-682 of the extracellular portion of HIV-1 gp41. The syncytium-inhibiting capacity of the immunopurified antibodies and their differential(More)
The current network architecture for mobile devices presents applications with a synchronous model and employs end-to-end connections. In reality, devices are often disconnected from the network and, while they are disconnected, they can connect to other devices in the neighborhood and exploit the connectivity to allow the user to continue to work. This is(More)
This paper presents an architectural solution for multimedia delivering over heterogeneous smart phones tailored to the needs of individual users. The system is based on the collection of Wi-Fi fingerprints in an environment, and sends multimedia data to the users' smart phones based on their interests, their location and their movement. This solution(More)
The steady increase in user demand for “all the time, everywhere access” asks for effective and portable solutions for mobility management. Traditionally, global mobility has been addressed by solutions at the network layer. This is the case of Mobile IP and related approaches. On the other hand, this class of solutions presents several drawbacks, such as(More)
Mobile communication is increasingly becoming part of everyday life. Haggle ( is an innovative project that exploits human mobility for creating an invisible social network to enable communication in the presence of intermittent network connectivity. Mobile devices equipped with network interfaces, may in fact (temporarily) be out of(More)
Traditionally, global network mobility problem is addressed at networking layer. However, none of these solution is designed for supporting seamless horizontal and vertical handover. The demonstrated solution, called WiOptiMo, provides always-on, continuous and optimized network services, whenever possible, to the applications independently from lower(More)
