Cognitive radio (CD) is one of the main parts of telecommunication communication systems (TCS-IOE) in connection with what was called to solve the problem of spectrum deficit and the introduction of intellectual functions. The choice of channel with multiple access of primary users (PCs) and secondary users (VCs) is one of the most important issues of the standard. Due to the competition of channels there is a mutual influence of packages of primary and secondary users. In order to reduce channel competition among secondary users, a method for choosing cognitive radio channels was developed at the multiple access of primary and secondary users using the technology "Energy Harvesting" under the control of the neural network. Based on the developed method, a hybrid model for data transmission under the control of the neural network for each secondary user was implemented. For this model there are properties in which a secondary user may randomly operate unregulatedly in combination with the occupied channels using the technology "Energy Harvesting" (EH) and the overlap. In addition, to implement the developed method, the criterion for choosing a channel based on competition among the multiple requests of secondary users for data transmission or the " Energy Harvesting" technology was determined. Based on this criterion, a competing set of sequences is created. The simulation shows that the proposed channel sharing method and the channel selection criterion outperform other methods in terms of false occupation (error), average throughput, average waiting time, and second-power energy efficiency.Downloads
