The fifth generation of mobile wireless communications, 5G, is expected to be a big revolution not only for information technologies, but also on the way we see the world, bringing not only great improvements in terms of data rate, but also extremely high capacity, extremely low latencies, high spectral and energy efficiency, among other great advances. In this context, 5G will enable paradigms such as the Internet of Things and Industry 4.0. However, with the massive growth of users and devices, the development of energy-efficient technologies is crucial for the network to become autonomous and intelligent. Thus, the technique known as energy harvesting is particularly attractive because it relies on the use of radio frequency waves as a source for energy supply. Therefore, it enables the transmission of information and energy simultaneously, which can result in several benefits and potentiate many of the expectations for 5G and future generations. In this sense, this project intends to analyze two techniques for simultaneous transmission of energy and information in the context of cooperative networks, where the relay is a node with energy limitations. The techniques used will be time-switching and power splitting, the same ones that will be addressed for the two modes of operation of the relay, half and full duplex. The optimal time intervals and power splitting factors will be investigated in order to minimize the outage probability or maximize the system throughput. In addition, a scenario regarding system security at the physical layer and the relationship with energy efficiency will also be analyzed. The evaluation will be carried out via Monte Carlo simulations implemented in simulation software such as Matlab or Octave and optimization tools from Matlab.
