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) • 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.
Potential Testbed Development - Software Architecture • 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
