Un equipo de investigadores de IMDEA Networks es autor de un artículo en el que propone y analiza una innovadora técnica para la gestión inteligente de recursos para futuras redes celulares. El artículo aparecerá en las actas de IEEE INFOCOM 2014 (33^rd Annual IEEE International Conference on Computer Communications), un congreso líder en la investigación sobre redes informáticas. Este trabajo – titulado Interference Coordination Strategies for Content Update Dissemination in LTE-A – es el resultado del esfuerzo conjunto de un Estudiante de doctorado, Vincenzo Sciancalepore, un Research Assistant Professor, Vincenzo Mancuso, y el Director Adjunto del Instituto, Albert Banchs. Shmuel Zaks, Cátedra Joan Callner-Miller de Informática en el Instituto de Tecnología Israelí Technion también ha contribuido a este trabajo. INFOCOM 2014 se celebrará en Toronto, Canadá, desde el 27 de abril al 2 de mayo de 2014.

Abstract:
Opportunistic traffic offloading has been proposed to tackle overload problems in cellular networks. However, they only address the problem of deadline-based content propagation in the cellular system, given wireless environment characterization. In contrast, we cope with the traffic offloading issue from another perspective: the base station interference coordination problem. In particular, we aim at the minimization of the total transmission time spent by the base stations in order to inject contents into the network, and we leverage the recently proposed ABSF technique to keep under control intercell interference. We formulate an optimization problem, prove that it is NP-Complete, and propose a near-optimal heuristic. Our proposed algorithm substantially outperforms classical intercell interference approaches proposed in the literature, as we evaluate through the simulation of dense LTE-A network scenarios.
