Two wireless networking researchers have authored one of the first textbooks devoted to the study of cognitive radio networks, an intelligent transmission technique that enhances efficiency in wireless communications.

Cognitive Radio Networks by Fei Hu, an assistant professor of computer engineering at Rochester Institute of Technology, and Yang Xiao, an assistant professor of computer science at the University of Alabama, provides information and applications related to cognitive radio technology for use in research and classroom settings.

Hu and Xiao hope the book will expand the development of applications in cognitive radio, which utilizes a network or wireless node that can change transmission or reception parameters to avoid interference from licensed or unlicensed users in the same frequency. Experts believe the technology may ultimately assist in improving transmission performance over different radio frequencies, particularly for security and military uses.

“The explosion of wireless communication over the last two decades has led to the need for spectrum-agile communications that are more efficient and less prone to interference from other radio transmissions,” notes Hu. “This type of technology is particularly important for military and security transmissions where clear, uninterrupted communication is essential.”

“Cognitive radio is still a nascent technology and researchers and students in the field require data and instruction related to best practices and technology applications,” adds Yang. “This book seeks to provide that information and enhance further development of the technique for use in a wide variety of wireless network settings.”
