Next generation communication networks will support high data rates, seamless connections, at higher and often heterogeneous quality-of-service levels, in scenarios with ever increasing mobility. To achieve these targets, resource allocation is a critical aspect for the implementation of such innovative communication networks since the allocation of communication resources influences not only physical layer performance measures such as the bit error rate or signal-to-noise ratio, but can also effect network level Quality of Service (QoS) parameters such as throughput, delay and loss. In this scenario, efficient allocation of the available resources play a strategic fundament role to increase and optimize communication performance of individual nodes or of the global network, and efficiently exploit the available frequency spectrum eventually admitting unlicensed users. The investigations involve researches and technicians from the physical, to the networking layers and above and eventually promote joint design within different layers (cross-layer design). Analysis and design of the complex interactions in future communications networks requires contributions from a variety of disciplines, which span from information theory to statistical physics, game theory, optimization, non-commutative algebras and so forth. The workshop promotes the applications of new methodologies in this field with the aim of providing the participants advanced and innovative tools able to catch the fundamental dynamics of complex interactions. It fosters the presentation of new protocols and schemes for resource allocation. The applications can steam from any wireless scenario, from multicell networks to sensor and relay networks, cognitive radio or ad hoc network. In fact, object of the workshop is to provide the participant with a comprehensive, thorough, and unified vision of the resource allocation issue in complex multiuser and multiprovider networks. The workshop will include a NEWCOM# Session where results of the European Network of Excellence in Wireless Communications NEWCOM# will be presented.
