Cognitive Radio

The scarcity of radio spectrum is one of the most urgent issues at the forefront of future network research that is yet to be addressed. To address the problem of spectrum usage efficiency, the cognitive radio (CR) concept was proposed. The challenges of employing CRs include ensuring secure device operations and data transmission with advanced computing techniques. Successful development of CR systems will involve attainment of the following key objectives:Increasing the rate and capacity of CR-based networksHow the power is utilized in CR hardware devices with CMOS circuitsHow the framework is needed in complex networksVedic multipliers on CR networksSpatial analysis and clustering methods for traffic managementTo transmit a large volume of data like video compressionSwarm optimization algorithmsResource sharing in peer-to-peer networkingThis book gathers the latest research works focusing on the issues, challenges, and solutions in the field of Cognitive Radio Networks, with various techniques. The chapters in this book will give solutions to the problems that Industry 4.0 faces, and will be an essential resource for scholars in all areas of the field.
