Innovative smart resource management technique for future cellular networks

10 February 2014

A team of IMDEA Networks researchers has authored an article in which they propose and analyze an innovative smart resource management technique for future cellular networks. The article will appear in the proceedings of IEEE INFOCOM 2014 (the 33rd Annual IEEE International Conference on Computer Communications), a leading conference in computer networking research. The work, Interference Coordination Strategies for Content Update Dissemination in LTE-A, is the result of joint efforts by a PhD Student, Vincenzo Sciancalepore, a Research Assistant Professor, Vincenzo Mancuso, and the Institute’s Deputy Director, Albert Banchs. Shmuel Zaks, Joan Callner-Miller Chair Professor of Computer Science at Technion – Israel Institute of Technology also contributed to this work. INFOCOM 2014 will meet in Toronto, Canada from April 27th to May 2nd, 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.
