HOBOKEN, N.J. ¯ The National Institute of Justice, which serves as the research and development arm of the US Department of Justice, has awarded a three-year project grant to Dr. Rajarathnam Chandramouli, Thomas E. Hattrick Chair Associate Professor of Information Systems in the Department of Electrical & Computer Engineering at Stevens Institute of Technology. Chandramouli will serve as Principal Investigator of the project, titled, "Cognitive radio protocols and platform for dynamic spectrum access in public safety bands."
"Recent studies, such as Project SAFECOM, have shown that radio spectrum is fragmented over space and time, leading to inefficient use of radio resources," said Chandrmouli. "Dynamic spectrum access using cognitive or intelligent radios allows users to share dynamically the available spectrum, to maximize spectral efficiency. In this project we propose to research and develop software defined radio-based cognitive radio technologies that facilitate public safety radios to occupy and dynamically release spectrum whenever and wherever they are available in the public safety bands. Protocols for spectrum aggregation to create a broadband connection for supporting quality of service for voice and data applications will be developed."
The proposed protocols will be implemented, tested and demonstrated in a software defined radio platform. Catastrophic loss of wireless links and graceful degradation will be emulated in the test bed to demonstrate the gains that can be achieved using the proposed technology.
"Finally," said Chandramouli, "we believe that this study will help us better understand the pros and cons of the FCC's spectrum policy reform."
Professor Chandramouli is the co-founder of the MSyNC Laboratory at Stevens, and he is an internationally recognized expert in the fields of cognitive radio networks and digital steganography/steganalysis. He serves as the Founding Chair of the IEEE COMSOC Technical Sub-committee on Cognitive Networks and also as a Management Board Member of IEEE SCC 41 that oversees the development of international standards for cognitive networks. Recently he co-founded with Stevens Professor K.P. Subblakshmi and Dr. Helena S. Wisniewski, Stevens' VP for Research & Enterprise Development, the Technogenesis® Company InStream Media LLC, which offers disruptive solutions for the future of embedded, non-invasive dynamic digital advertising, among other applications.
About the National Institute of Justice
The National Institute of Justice (NIJ) is the research, development, and evaluation agency of the US Department of Justice and is dedicated to researching crime control and justice issues. NIJ provides objective, independent, evidence-based knowledge and tools to meet the challenges of crime and justice, particularly at the State and local levels.
The NIJ Director is appointed by the President and confirmed by the Senate. The NIJ Director establishes the Institute's objectives, guided by the priorities of the Office of Justice Programs, the U.S. Department of Justice, and the needs of the field. The Institute actively solicits the views of criminal justice and other professionals and researchers to inform its search for the knowledge and tools to guide policy and practice.
