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 demonstrate the vehicular sensing and control (VSC) platform prototype in this GEC. The platform is designed to enable researchers and experimenters to evaluate the VSC networking research in real world. Towards better understanding of our platform and related technologies, several applications also expect to make their debut in GEC 19. By doing this, we hope to get feedbacks and comments for further improvement and extension.

We will demonstrate Vehicular Sensing and Control (VSC) platform that we designed for researchers and experimenters to support idea/protocol experimentation and emulation in a real world. Specifically, by leveraging the GENI resources,(i.e. GENI WiMAX network, ExoGENI racks, VLAN connection as well as relevant experimenter tools), this platform enables the researchers and experimenters to use OpenXC sensing and camera-based sensing data such as vehicle location, vehicle speed, pedal position, traffic states surrounding the vehicle as input for the experimentation and emulation. It could be very helpful to reason about the protocol design. In this demo, we will highlight the latest mechanisms developed for VSC application-layer emulation and extensive experimental results that we collect using the VSC platform. The audience with the interests of vehicular network should stop by and see this demo given the capability of the VSC platform.
