“…Moreover, the outage probability becomes worse for a larger number of interference signals M. However, for high values of a, the influence of the number of interference signals and threshold power diminishes. The outage probability is then determined by the approximate expression in (21), that is, by the parameter values of the first hop. In this case, the number of interference signals, that is, the interference power at the destination, and P th do not have a significant influence on the outage probability.…”

“…However, both papers considered the linear energy harvester model, which might be impractical in realistic scenarios owing to the nonlinearities of the electronic components, as recently reported in [19], [20]. Analyses of AF and DF relaying networks with a nonlinear model were provided in [21] and [22], respectively. Still, these papers do not consider the impact of the CCI signals on the performance of the energyharvesting relaying system.…”

A decode-and-forward system with an energyharvesting relay is analyzed for the case when an arbitrary number of independent interference signals affect the communication at both the relay and the destination nodes. The scenario in which the relay harvests energy from both the source and interference signals using a time switching scheme is analyzed. The analysis is performed for the interference-limited Nakagami-m fading environment, assuming a realistic nonlinearity for the electronic devices. The closed-form outage probability expression for the system with a nonlinear energy harvester is derived. An asymptotic expression valid for the case of a simpler linear harvesting model is also provided. The derived analytical results are corroborated by an independent simulation model. The impacts of the saturation threshold power, the energy-harvesting ratio, and the number and power of the interference signals on the system performance are analyzed.

“…It is characterized by a large distance separating transmitter and receiver. Several statistical models are used to describe fading in wireless environments and the most frequently used distribution for large scale fading is shadowing, while for small scale fading, Rayleigh, and Ricean [19] can be used. These statistical models are used to accurately predict the fading effect.…”

In this paper, we investigate a joint power allocation and relay selection scheme for energy efficient cooperation in energy harvesting-wireless sensor networks (EH-WSN). We mainly propose a simple heuristic algorithm to improve the energy efficiency of each node in a clustering based EH-WSN. First, the effect of cooperative communication is evaluated, and then, the energy sustainability of every node is taken into account, finally, we formulate an online optimization problem which can be solved near optimally with low computational complexity. Extensive simulation results are presented to show the outstanding performance of our proposed scheme in nodes' transmitting power allocation and average working utility. Therefore, this joint optimization algorithm has a promising future in real applications.
