Brief demo description: Demonstration of wide-band radio transceiver for the GENI CogRadio system. The demonstration will highlight the WDR (Wide Dynamic Range) radio operating on an FPGA platform. Signal analyzers will demonstrate the system operating at 100MHz, 400MHz, 900Mhz and 2400MHz on a combination of cabled connections (for licensed bands) and free space (for unlicensed bands). The demonstration will also include a poster detailed the software infrastructure employed.

Demo Title: Wide-Area Monitoring of Power Systems Using DHT and GENI-Based Cloud Computing

One-sentence layman's description: This demo will show how enhanced distributed hash tables (DHTs), deployed in a distributed cloud network like GENI, can be used as a highly useful medium for real-time distributed monitoring of very large power systems using massive volumes of Synchrophasor data.

Who should see this demo? Any attendee (graduate students, postdoctoral researchers, professors and industry partners) who are interested in smart grids, distributed computing and real-time systems.

Demo description paragraph(s): The demo will show how enhanced distributed hash tables can be deployed in a distributed cloud network like GENI to form a transformatively new wide-area communication medium for executing critical, real-time monitoring and estimation functions in large electric power systems using massive volumes of Synchrophasor data. We will demonstrate how various monitoring and state estimation algorithms for keeping continuous track of a power grid, can be installed in GENI using a deadline-driven DHT system we are developing, which decouples the data communication between the grid sensors (Phasor Measurement Units or PMUs), the data processors (Phasor Data Concentrators or PDCs), and the monitoring applications. We will develop a dynamic, virtual PMU-PDC architecture in ExoGENI that can be connected to a power system testbed running at the NSF FREEDM Systems Center, located at NC State University. The connection will be completely plug-and-play. We will use this interconnection to emulate several realistic monitoring scenarios, and evaluate how DHTs can improve the resiliency of monitoring against network delays and malicious data-flows. This is a collaboration between RENCI and NCSU.

We will show how real-time simulation enables interaction between real machines and the simulator. SeattleGENI will be used as means to launch simultaneous commands from containers attached to our simulator. Also, we will show how our GUI tool called Slingshot is used to receive updates and change simulation states in real-time.
