The scarcity of radio spectrum is one of the most urgent issues at the forefront of future network research that has yet to be addressed. In order to address the problem of spectrum usage efficiency, the cognitive radio (CR) concept was proposed. The challenges of employing CR’S include that of ensuring secure device operations and data transmission with advanced computing techniques. Successful development of CR systems will involve the attainment of following key objectives:
- Increasing rate and capacity for CR-based networks
- How the power is utilized in CR hardware devices with CMOS circuits
- How the Frame work is needed in complex networks
- Vedic multipliers on CR Networks
- Spatial analysis and clustering methods for traffic management
- To transmit large volume of data like video compression
- Swarm optimization algorithms
- Resource sharing in peer to peer networking
This book gathers together 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 facing Industry 4.0 and will be an essential resource for the scholars in all areas of the field.
