Update and Plan for Spring 2011 Yi Guo, Zheng Wang, Wenlin Zhang RavenShield Weekly Meeting Jan. 24, 2011
2
Agenda Personnel changes Feedback from the IPR meeting and discussion of ideas Plan for Spring 2011
3
Centralized vs. Distributed Spectrum Sensing Centralized Scheme: – Fusion center (common receiver) – Reporting channels Distributed Scheme: – Local information exchange without the central station
4
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.
5
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.
6
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
