Visualizing real-time radio spectrum access with CORNET3D

Modern web technology enables the 3D portrayal of real-time data. WebSocket connections provide data over the web without the time-consuming overhead of HTTP requests. The server-side "push" paradigm is particularly useful for creating novel tools such as CORNET3D, where real-time 3D visualization is required. CORNET3D is an innovative Web3D interface to a research and education test bed for Dynamic Spectrum Access (DSA). Our system can drive several 2D and 3D portrayals of spectral data and radio performance metrics from a live, online system. The testbed can further integrate the data portrayals into a multi-user "serious game" to teach students about strategies for the optimal use of spectrum resources by providing them with real-time scoring based on their choices of radio transmission parameters. This paper describes the web service architecture and Webd3D front end for our DSA testbed, detailing new methods for spectrum visualization and the applications they enable.
