Update and Plan for Spring 2011
Yi Guo, Zheng Wang, Wenlin Zhang
RavenShield Weekly Meeting Jan. 24, 2011
Agenda
• Personnel changes• Feedback from the IPR meeting and discussion of
ideas• Plan for Spring 2011
Centralized vs. Distributed Spectrum Sensing
• Centralized Scheme:– Fusion center (common
receiver) – Reporting channels
• Distributed Scheme:– Local information
exchange without the central station
Potential Testbed Development(In collaboration with Profs. Yingying Chen and Yu-Dong Yao)

WiMax NetworkTV Band
3G Network
Secondary User (USRP)
About 10 - 20 USRPs are needed (currently 4 available). Using Agilent signal generator to simulate different kinds of signal band, e.g., TV band, 3G, etc.

– Mobility Control Component: Controlling the mobility of the primary or secondary users in the system;
– Spectrum Sensing Component: Sensing the spectrum usage for different kinds of wireless networks;
– Application-specific Component: Applying different functionality in the system.
Next Step
• Theoretical proof of the proposed distributed consensus-based spectrum sensing algorithm
• Extensive simulations• Performance comparisons• A comprehensive report and a GLOBECOM paper
(deadline March 1, 2011)
• Laboratory testbed development
