Cognitive Radio

Project Brochure New

The large population of connected devices imposes a great demand on spectrum resource, which is now crowded with most frequency segments being statically and exclusively allocated to specific types of wireless devices. On the other hand, at any given time and place, less than 10 percent of the allocated spectrum is being utilized. Cognitive Radio is the next generation technology option further increase availability of spectrum by using these unused spectrum (white spaces/ spectrum holes) efficiently, opportunistically, and dynamically without causing any unacceptable interference to the licensed primary user. While the cognitive sensing has been investigated in recent years, there is a need to develop sophisticated methods that are reliable at low SNRs. There has been relatively less work on upper layer issues, such as the effects of distributed transmit power control, packet error rate and quality of service guarantee, as well as device level issues, such as energy constraints. Further, studies on the usage of cognitive radios for mobile medical health-care support are quite nascent. This project envisages a comprehensive approach to the design issues related to architectural planning, physical layer alternatives and their impact, medium access protocols and network layer processing including dynamic spectrum coordination, energy efficiency, individual and group mobility support, and broadband service provisioning on low-power flexible cognitive radio platform. In view of an urgent need for technologies for national-level mobile health-care support, and the fact that there has been no significant ongoing effort in the country on such technology development, application areas in this research project would fill this gap.
