Planning and Development for Spring 2011 Spectrum Sensing Initiatives

The agenda for the RavenShield weekly meeting on January 24, 2011, focuses on personnel changes, insights from the IPR meeting, and plans for Spring 2011 relating to centralized versus distributed spectrum sensing. The presentation includes details on testbed development, requiring 10-20 USRPs, and utilizing an Agilent signal generator for signal simulation across various bands. Future steps involve proving a distributed consensus-based spectrum sensing algorithm, performing simulations and comparisons, and preparing a comprehensive report and GLOBECOM paper by the March 1, 2011 deadline.

Presentation Transcript

  1. 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
