Smart grids (SG) represent the next step in modernizing the current electric grid. In this structure, a communications network is combined with the power grid in order to gather information that can be used to increase the efficiency of the grid, reduce power consumption, and improve the reliability of services, among other numerous advantages.

Enabling Energy Harvesting (EH) for Cognitive Radio Networks (CRNs) is promising to extend their lifetime. Since Secondary Users (SUs) can either access the spectrum or harvest energy, EH should be integrated within the context of Dynamic Spectrum Access (DSA), in order to increase both the energy efficiency and the spectrum efficiency. This paper proposes(More)
The efficiency of Cognitive Radio Networks (CRNs) depends on the used spectrum allocation algorithms. In this paper, we propose a new Dynamic Spectrum Allocation (DSA) algorithm that jointly considers the geographical locations of the nodes along with fading, quality of the communication links, interference between the primary and the secondary networks,(More)
Allowing Secondary Users (SUs) to access the licensed spectrum without causing harmful interference to the Primary Users (PUs) is crucial in enabling the Cognitive Radio (CR) technology. In order to increase the utilization of the spectrum bands, we propose a Dynamic Spectrum Allocation (DSA) algorithm that integrates both interweave and underlay spectrum(More)
