Dr. Chandramouli has been awarded grant by the Office of Justice Programs of the Department of Justice for his Project titled "Cognitive radio protocols and platform for dynamic spectrum access in public safety bands."
Recent studies (e.g., Project SAFECOM) have shown that radio spectrum is fragmented over space and time leading to inefficient use of radio resources. Dynamic spectrum access using cognitive radios allow users to dynamically share the available spectrum to maximize spectral efficiency. The project proposes to research and develop software defined radio based cognitive radio technologies that facilitates public safety radios to dynamically occupy and 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, this study will facilitate a better understanding of the pros and cons of FCC's spectrum policy reform.
