  In the future standardization of the 5G networks, in Long Term Evolution
(LTE) Release 13 and beyond, Device-to-Device communications (D2D) is
recognized as one of the key technologies that will support the 5G
architecture. In fact, D2D can be exploited for different proximity-based
services (ProSe) where the users discover their neighbors and benefit form
different services like social applications, advertisement, public safety, and
warning messages. In such a scenario, the aim is to manage in a proper way the
radio spectrum and the energy consumption to provide high Quality of Experience
(QoE) and better Quality of Services (QoS). To reach this goal, in this paper
we propose a novel D2D-based uploading scheme in order to decrease the amount
of radio resources needed to upload to the eNodeB a certain multimedia content.
As a further improvement, the proposed scheme enhances the energy consumption
of the users in the network, without affects the content uploading time. The
obtained results show that our scheme achieves a gain of about 35\% in term of
mean radio resources used with respect to the standard LTE cellular approach.
In addition, it is also 40 times more efficient in terms of energy consumption
needed to upload the multimedia content.
