Ubiquitous networks are a key element of the Future Internet since they guarantee users access to Internet services anytime, anywhere, without any pre-existing network infrastructure. Users’ devices (cell phones, palm computers, mp3 readers, etc.) will not only connect to the Internet to access information, but will actually become part of the network itself, providing content and services by means of the emerging peer-to-peer paradigm (e.g. eMule and BitTorrent). Research in this field focuses on advanced solutions for networking and data management in ubiquitous networks composed of fixed and mobile portions of a heterogeneous nature: from networks consisting of user devices alone, to sensor networks scattered throughout the surrounding physical environment.
