Accés obert
In this paper, we present a procedure for switching on and off base stations (BSs) that are powered with solar panels and have finite batteries. In the scenario under consideration it is considered that the BSs are placed ...
Optimization of radio and computational resources for energy efficiency in latency-constrained application offloading
(2015-10)
Article.
Accés obert
Article.
Accés obert
Providing femto access points (FAPs) with computational capabilities will allow (either total or partial) offloading of highly demanding applications from smartphones to the so-called femto-cloud. Such offloading promises ...

In this paper, we present an asymptotic analysis of the behavior of a network where the mobile terminals are considered to be battery-powered devices provided with energy harvesting capabilities. The asymptotic analysis ...
Sparse multiple relay selection for network beamforming with individual power constraints using semidefinite relaxation
(2016-02)
Article.
Accés obert
Article.
Accés obert
This paper deals with the multiple relay selection problem in two-hop wireless cooperative networks with individual power constraints at the relays. In particular, it addresses the problem of selecting the best subset of ...
Joint optimization of power and data transfer in multiuser MIMO systems

This paper addresses the margin adaptive problem for the filter bank multicarrier (FBMC) modulation based on the offset QAM (OQAM), referred to as FBMC/OQAM. The analysis conducted in this paper reveals that due to the ...
Energy consumption optimisation for duty-cycled schemes in shadowed environments
(2014-05-28)
Article.
Accés obert
Article.
Accés obert
The focus of this study is the optimal configuration of a wireless low-power duty-cycled network with respect to the minimal energy consumption. Precisely, the energy consumption of a truncated-ARQ scheme in realistic ...
