Repositório Comum (40.364 recursos)

É um repositório para instituições de ensino e investigação produtoras de literatura científica cuja dimensão ainda não justifica a criação de um repositório próprio. Permite integrar instituições, grupos ou indivíduos na infra-estrutura do projecto, nomeadamente através das pesquisas do Portal RCAAP e da B-On.

  3. Physical Layer Aware Network Architecture for the Future Internet

    Cardoso, Filipe; Correia, Luís; Mannersalo, Petteri; Frantti, Tapio; Serrador, António; Nunzi, Giorgio; Genay, Naveena; Le Rouzic, Esther
    In this article, physical layer awareness inaccess, core, and metro networks is addressed,and a Physical Layer Aware Network Architec-ture Framework for the Future Internet is pre-sented and discussed, as proposed within theframework of the European ICT Project4WARD. Current limitations and shortcomingsof the Internet architecture are driving researchtrends at a global scale toward a novel, secure,and flexible architecture. This Future Internetarchitecture must allow for the co-existence andcooperation of multiple networks on commonplatforms, through the virtualization of networkresources. Possible solutions embrace a fullrange of technologies, from fiber backbones towireless access networks. The virtualization ofphysical networking resources will enhance thepossibility of handling different...

  4. Energy Efficient TransmissionTechniques for LTE

    Cardoso, Filipe; Petersson, Sven; Boldi, Mauro; Mizuta, Shinji; Dietl, Guido; Torrea-Duran, Rodolfo; Desset, Claude; Leinonen, Jouko; Correia, Luís
    The goal of the European ICT ProjectEARTH is to enhance energy efficiency of cur-rent LTE cellular networks by 50 percent,enabling operators to provide more extensivecoverage, namely to less densely populatedareas, while ensuring high levels of efficiency,hence, reducing the carbon footprint. In order toachieve this objective, different strategies, at dif-ferent levels, are being addressed. Energy effi-cient transmission techniques for LTE, proposedwithin the framework of EARTH, are addressedand discussed, with an emphasis on beamform-ing and MIMO. It is concluded that the strategicobjective of EARTH is achievable. CombinedMIMO mode selection, resource allocation,scheduling and precoding strategies will allow anenergy consumption reduction of more than...
