Software Defined Radio, Cognitive Radio, Cognitive Networks: Current Research Efforts and Future Trends

Talk Title: Software Defined Radio, Cognitive Radio, Cognitive Networks: Current Research Efforts and Future Trends

Abstract: Wireless networks have been well studied and optimized with traditional radio resource management techniques, but still there is room for improvement. Cognitive radio technology can bring significant network improvements by providing awareness to the surrounding radio environment, exploiting previous network knowledge and optimizing the use of resources using machine learning and artificial intelligence techniques. Cognitive radio can also co-exist with legacy equipment thus acting as a bridge among heterogeneous communication systems. In this seminar, an introduction to the concepts of software defined radio, cognitive radio and cognitive networks is presented. An approach for applying cognition in wireless networks is described. Current research efforts in the area and future trends in the area are discussed.

Biography: Dr. Lizdabel Morales‐Tirado received her Bachelors of Science in Electrical Engineering from the University of Puerto Rico Mayagüez Campus in 1996. She received a Master of Science in Electrical Engineering from Northwestern University in 1998 and her Doctor in Philosophy in Electrical Engineering in the January 2010 from Virginia Polytechnic Institute and State University (Virginia Tech).

She is currently an assistant professor at the University of Puerto Rico in Mayagüez (UPRM) in the Department of Electrical and Computer Engineering. She teaches courses in communications, and is conducting research in the areas of wireless communications, cognitive radio and cognitive networks. Her newly formed research group, the Intelligent Wireless and Networked Communications Laboratory (iWiNC), currently is composed of one graduate student and eleven undergraduate students.

Dr. Morales is a GEM Fellow, a Virginia Space Grant Consortium Fellow and a John Lee Pratt Fellow. She is also co‐founder of Divergent Engineering Inc., an engineering consulting company in Puerto Rico. Prior to attending Virginia Tech, Dr. Morales was an instructor at the Interamerican University in San Germán, Puerto Rico. She also worked as a Systems Engineer for Lucent Technologies from 1999 to 2001; and at Motorola's iDEN group from 1995 until 1999.
