  • Spectrum Decision Support System (SDSS) 2010 - 2012: SDSS provides an intelligent spectrum decision strategy for CR networks. This strategy integrates different decision making algorithms together and takes into account various characterization parameters of radio environment. The objective is to develop a scientific framework, based on which the numerical analysis, simulation evaluation and practical implementation can be done.

 

  • PlantLab Automatic Control System (PLACS) 2009 - 2010: PLACS is able to automatically control PlanetLab based P2P experiments. The goal is to solve the four fluctuation problems (founded in the PlanetLab environment), i.e., the connectivity, bandwidth, latency and hardware-utilization fluctuations.

 

  • Open BitTorrent Library (OBTL) 2009 - 2010: OBTL is a P2P client based on BitTorrent protocol, and it can run on Windows/MacOS/Linux operating systems. The example of using OBTL is to evaluate the performance of a new mechanism suggested for the P2P based multimedia streaming in PlanetLab environment.
