I would like to thank the IEEE for allowing the DySPANSC material to be included in this book. I also would like to thank Dr. James Stevens, the networking fellow at Collins Aerospace, and Dr. Thomas Tapp, the product owner of DSA capabilities at Collins Aerospace for their valuable input to this book. The DySPANSC material made this book a comprehensive reference for engineers developing DSA systems and Dr. Stevens's and Dr. Tapp's reviews and suggestions added so much value to this text.

Dr. George F. Elmasry was born in Egypt and received a Bachelor of Science in Electrical Engineering and Electrophysics from Alexandria University, Egypt in 1985. He then went on to receive a Master of Science and a PhD in Electrical Engineering from the New Jersey Institute of Technology (NJIT) in 1993 and 1999, respectively. Dr. Elmasry has over 25 years of industrial experience in commercial and defense telecommunications and is currently part of the Advanced Technology Center of Collins Aerospace, which is a forwardlooking research and development organization for defense and commercial aerospace telecommunications systems.

Dr. Elmasry has an interdisciplinary background in electrical and computer engineering and computer science. He is active in research, patenting, publications, grant proposals as well as system engineering of defense and commercial aerospace wireless communications systems. He has experience with technical task leads, team building and management. Dr. Elmasry has over 50 peerreviewed publications and countless patents that pertain to network resource management, network management, network operation, software defined radios, cognitive networking, resilient communications and network and transport layers algorithms.

Dr. Elmasry has authored a book on tactical wireless communications and networking that has been used as a textbook for graduate and senior level courses in different universities in the United States and internationally. He also authored part of the McGrawHill encyclopedia on the history of military radios.

In addition to his publications and patents activities, Dr. Elmasry has been a technical member of the annual Military Communications Conference (MILCOM) since 2003, where he has participated in session organization, paper reviews and session chairing. Dr. Elmasry is also a senior member of the Institute of Electrical and Computer Engineering (IEEE), a member of the Armed Forces Communications and Electronics Association (AFCEA) International, a Member of Sigma Xi and a member of Alpha Epsilon Lambda, the NJIT graduatestudent honor society. Dr. Elmasry holds countless awards, including the prestigious Hashimoto Award for achievement and academic excellence in electrical and computer engineering.

The coupling of spectrum sensing and dynamic spectrum access (DSA) solely with cognitive radios can do a disservice to the wireless communications community. Long before the concept of cognitive radios was coined, the defense community had elaborate spectrum sensing techniques. Since World War II, the defense community have had signal intelligence (SigInt) capabilities that are decades ahead of the commercial world's sensing capabilities. In today's commercial wireless system, we have the concept of finding the geolocation of a spectrum emitter through using multiple receivers (sensors) that can estimate the geolocation of the emitter and the direction of the emitter's beam. The defense community had this concept implemented in SigInt decades before the commercial world understood it and without having preknowledge of the emitted signal characteristics. SigInt capabilities used spectrum sensors extensively as part of the catandmouse game of detecting the enemy's spectrum emission and overcoming the enemy's jammers.
