— We propose a new multiple description (MD) coder design based on the Adaptive Multi-Rate Wideband (AMRWB) coder that can support transcoding-free communication between an ad-ho...
We report a first-of-its-kind realization of directional transmission for smartphone-like mobile devices using multiple passive directional antennas, supported by only one RF chai...
Services in pervasive computing systems must evolve so that they become minimally intrusive and exhibit inherent proactiveness and dynamic adaptability to the current conditions, u...
