NEWCOM++ is the acronym of a proposed Network of Excellence in Wireless COMmunications, submitted to Call 1 of the VII Framework Programme under the Objective ICT-2007.1.1: The Network of the Future, mainly in its target direction "Ubiquitous network infrastructure and architectures". The current proposal draws inspiration, shape/form, and substantive direction from its successful predecessor, the NoE NEWCOM, which was approved and funded by the EC for 36 months starting March 1st, 2004 and ending February 28, 2007. At the same time, NEWCOM++ aspires to inject new vision, expanded roles, ever-higher degrees of research integration, and a definitive roadmap to financial security for the long-term life of this undertaking in the European research and higher-learning space. The core concept of NEWCOM++ is that of an NoE of medium size, greatly reduced from the initial NEWCOM Consortium, formed by keeping the most committed and performing partners, exploiting the successful integration tools that NEWCOM designed and activated, and which is created for the purpose of scientifically addressing medium/long term, complex, interdisciplinary, fundamental research problems in the field of wireless networks, focused towards identifying, posing in the right modelling perspective, and at least partially characterizing the information-communication theoretical limits. Its main objectives are: Identify a selective set of scenarios, Define suitable performance measures that take into account the wireless channel nature, Perform a detailed analysis of the main theoretical results available, Evaluate information-theoretical bounds on the achievable performance, Design and analyze transmitting/receiving algorithms and protocols in order to approach those limits, Analyze implementation aspects of the above algorithms in flexible, energy-aware user terminals, Output the major findings into an integrated simulation library, Enhance the already good cooperation level among research
