Wirelessly Powered Cognitive Radio Communication Networks

—Many energy harvesting techniques have been investigated in the literature to solve the limitation of power supply problems as it has been one of the crucial challenges in wireless communication networks. With the relatively large numbers of sensors that are expected to be deployed in the upcoming Fifth Generation (5G) and Internet-of-Things (IoT), it has become harder to implement reasonably priced networks with the normal power supplying techniques. In this paper, a proposal of a Cognitive Radio Network (CRN) is presented where the SUs have the ability of Secondary-Users (SUs) to wirelessly harvest energy from a broadcasted energy which is sent from a Central Node (CN). Additionally, the nodes that might not get sufficient energy from the CN are considered and solved by letting other near nodes relay some of the harvested energy to those do not get sufficient energy from the initial broadcast. This maintains a fair distribution of energy among all the cognitive radio nodes in the network. The individual and overall network throughput is derived and investigated as well in order to validate the amount of transmitted data in the network.
