Prof. Song receives NSF grant to discover 4D volcano tomography
Source: GSU CS News, Sep 30th, 2011
The National Science Foundation has awarded a $1.83M grant
VolcanoSRI is a large-scale sensor network of low-cost geophysical stations that analyzes seismic signals and computes real-time, three-dimensional fluid movement within the volcano conduit system below the active network. The computed 4D tomographic model will illuminate complex, time-varying dynamics of an erupting volcano, providing a deeper scientific understanding of volcanic processes, as well as a basis for rapid detection of volcanic hazards. VolcanoSRI will potentially make the fictional holographic projector, known as Virgil in the film "Supervolcano", a non-fiction reality. In the final year of the project, we will undertake a 500 node sensor array deployment at an active volcano in Ecuador with the goal of running the network for a full deployment season, up to three months.
Implementing VolcanoSRI requires transformative innovation in the science of complex volcano systems in conjunction with the design of large-scale sensor networks. Our approach integrates innovations on distributed tomographic algorithms, collaborative signal processing, and situation-aware networking technology for large-scale, real-time sensor systems. The distributed tomography algorithm disperses the computational burden to the sensor nodes and performs real-time tomographic inversion within the network. The new approach, never attempted before, represents a major advance for both earth and computer science. The team is composed of computer and earth scientists, including early pioneers of wireless sensor networks as applied to volcano monitoring.
VolcanoSRI holds vast potential for real-time risk monitoring and development of early-warning systems for volcanoes and other earth hazards. The approach developed in VolcanoSRI is general, and can be implemented as a new network paradigm for other sensor-network applications, including oil-field exploration, structural engineering, and biomedical-health monitoring. The educational activities of this project include enhancing undergraduate and graduate curricula as well as research programs at the three collaborating universities. Through this project, the PI's will broaden access to course materials by providing the lectures, readings, and assignments in an open forum online to the public. The project provides many student opportunities for cross-disciplinary collaboration in engineering, earth and computer sciences, encouraging involvement of women and minorities.

Prof. Song receives NSF grant to study Smart Grids
Source: GSU CS News, Sep 14th, 2011
The National Science Foundation has awarded a $1.87 million grant to a team of researchers from Cornell, Georgia State University, and the University of California, Berkeley, to study foundational issues related to the development of smart grids.
The multidisciplinary research team includes four faculty members from Cornell: Dr. Lang Tong and Dr. Robert Thomas from the School of Electrical and Computer Engineering, Dr. Ken Birman from the Department of Computer Science, and Dr. Tim Mount from the Dyson School of Applied Economics and Management, with Dr. Tong serving as principal investigator. The principal investigator at UC Berkeley is Dr. Pravin Varaiya of the Department of Electrical Engineering and Computer Sciences. At GSU, the principal investigator is Dr. WenZhan Song, an associate professor in the Department of Computer Science and director of the Sensorweb Research Laboratory. GSU will receive $246,453 from the four-year Collaborative Research grant, which was funded by NSF’s Cyber-Physical Systems program.
The electric grid in the United States has evolved over the past century from a series of small independent community-based systems to one of the largest and most complex cyber-physical systems in the world. However, the conditions that made the grid an engineering marvel are being challenged by major changes, including worldwide efforts to address issues of sustainability and climate change. The NSF project focuses on building a foundation for future cyber-physical energy systems, known as smart grids. In the long term, the project’s goal is to support the development of renewable energy sources and community based micro-grids and to promote the widespread use of electric cars and smart appliances.
The team's research plan is divided into three parts. One is the design of a cloud computing architecture for scalable, consistent, and secure operation of smart grids. The second is the investigation of an information hierarchy for smart grids, with the goal of gaining an understanding of how information should be partitioned, collected, distributed, compressed, and aggregated. The final part of the project is the development of an open and scalable experimental platform for empirical investigation and testing of algorithms and concepts developed in the project. This platform, known as SmartGridLab, will combine a hardware testbed with a software simulator, allowing software virtual nodes to interact with physical nodes in the testbed. Dr. Song and his students will develop SmartGridLab at GSU.
Prof. Song received two new industrial funding
Source: GSU CS News, June 2nd, 2011
Dr. Wen-Zhan Song received a 4-year grant for $144,144 from the Korea Food Research Institute (KFRI) for a project titled "Development of USN Sensor Node to Control Food Quality", together with Dr. Deuk Heo at Washington State University. In this project, they will develop an integrated RFID wireless sensor node (RWSN) to control the quality of food in logistics. Nowadays, monitoring one or two environmental factors is not enough to meet the demand for quality control of food in logistics. The system which can monitor several environmental factors, such as temperature, humidity and shock, can guarantee high level of quality control of food. In addition, both wireless interfaces of RFID and ZigBee will be incorporated with WSNs to increase the coverage of wireless sensor network and to enhance the interoperability of wireless communication methods operating with both of RFID and ZigBee. The goal of the research is to design an integrated RFID wireless sensor node (RWSN) to monitor and to control the quality of food in logistics and middleware for the proposed sensor nodes.
Dr. Wen-Zhan Song has also received an industrial gift money for $3600 from AVYZO Systems Inc. Dr. Song has been helping AVYZO to develop a Water-meter Sensor Network Prototype. Today, many small water leakage in houses and buildings is undetected for years and wastes significant amount of water daily. Many times, water leak can only be found when the leakage is visually noticed. The ultimate solution is water submetering, where individual low-cost meters are installed in each apartment and linked through a wireless system. The Water-meter Sensor Network Prototype will allow for real-time fine-scale meter reading from anywhere anytime. It will greatly help the society to save water resources and reduce water cost.

Also, WSU News on June 8th, 2010: Spider Sensors Helping Predict Volcanic Activity
WSU Joins with NASA JPL, USGS CVO in High-Tech Monitoring of Mount St. Helens
by Jet Propulsion Laboratory, Pasadena, California, August 07, 2009.
Scientists have placed high-tech "spiders" inside and around the mouth of Mount St. Helens, one of the most active volcanoes in the United States. Networks such as these could one day be used to respond rapidly to an impending eruption.
On July 14, 2009, these spider pods were lowered by cable from a helicopter hovering about 100 feet up (30 meters) and gently put in hot spots inside and around the volcano crater.
"This project demonstrates that a low-cost sensor network system can support real-time monitoring in extremely challenging environments," said WenZhan Song of Washington State University Vancouver. Song is the principal investigator for this NASA-funded technology research project, which also draws on participation from the U.S. Geological Survey and from NASA's Jet Propulsion Laboratory, Pasadena, Calif.

Monitoring Mount St. Helens: "Spiders" spin web around volcano
by Erik Robinson Columbian Staff Writer, Thursday,July 16, 2009.
On Tuesday morning, a bevy of scientists clustered around a set of 14 peculiar silver boxes in a gravel parking lot near Mount St. Helens.
Anticipation was high as the group waited for the sun to burn through a blanket of low-hanging clouds. A helicopter waited nearby to hoist the packages into the volcano’s steaming crater and around the mountain flanks, putting the sensors into position to measure every volcanic hiccup.
Once in place, the probes would form their own communication network.

High-tech eyes keep watch on Mount St. Helens
MOUNT ST. HELENS, Wash. -- Researchers have come up with a way to keep a close eye on Mount St. Helens without stepping foot on the crater.
Geologists call them "spiders" -- pods that are small and tough enough to reach places no man dares, like the vent on the volcano.
"Nobody really wants to go in there and dig in a new instrument. It's too much risk," said Rick LaHusen with the U.S. Geological Survey. Each stainless steel box is a self-contained volcano laboratory that sends instant data for immediate analysis.
GPS units detect movements down to the centimeter. Lead plates pick up even tiny foot taps. And pressure gauges sense small explosions.
On Tuesday a dozen spiders were hooked to a helicopter and put in place on North America's most active volcano.
The flight into the crater was the culmination of a 2-year, $2 million partnership between the U.S. geological survey, Washington State University and NASA. The space agency isn't so much interested in the volcanoes as the spiders, including how they communicate with each other and satellites in space.
"They share a network. They automatically find a network and a route out somewhere to the observatory," LaHusen said.
By talking to each other, the spiders also determine which information is most important and which spider has priority.
"You don't have to go and reconfigure each one. You don't have to hike up the volcano and do this, or fly up the volcano and start tinkering with it," said Sharon Kader of NASA's Jet Propulsion Laboratory.
After blanketing Mount St. Helens, the next step is putting a series of $3,000 spiders on other volcanoes. With some fine-tuning, geologists say spiders could become the cheapest, safest way to predict an eruption. Click this link for the news
Mesh Network Monitors Volcanoes
Sensors dropped onto Mount St. Helens relayed data after forming an ad-hoc network.
by Kristina Grifantini, MIT Technology Review Magazine, Monday, June 22, 2009
Today kicks off the three-day MobiSys 2009 conference in Krakow, Poland--a showcase of emerging mobile and wireless technology. And one paper that caught my eye comes from Washington State University and the U.S. Geological Survey. WSU Researchers will present a paper that shows how an air-dropped mesh sensor network can monitor volcanoes in real time.
Traditionally, scientists have had to use data loggers and permanent installations to send volcanic data back to observatories. But the WSU researchers dropped five mobile stations via helicopter, each 2 kilometers apart, on treacherous terrain on Mount St. Helens in Washington State. Despite rain, snow and over 120 mph winds, the stations formed a mesh network to successfully relay real-time data for a month and a half. Each mobile station is a three-legged structure, about a meter tall 3 kilograms. Inside is a battery-powered iMote2 platform, a GPS receiver, and sensors. The team used an accelerometer to detect seismic activity, an infrasonic sensor to capture low-frequency acoustic waves resulting from eruptions, and a lightning sensor that can detect strikes up to 10 kilometers away. Each node automatically increases the number of samples it takes once it detects an event. But a user can configure and control the sensors via the Web.
Lead researcher and assistant professor at WSU Wen-Zhan Song says that the rapidly deployable system, "has particular value during periods of volcanic unrest but is also useful for longer term monitoring." Click this link for the news
"Spider" technology guards Mount St. Helens volcano
by BARBARA LABOE, The (Longview) Daily News, May 19, 2009, 06:34 AM
Humans are not the only ones pondering Mount St. Helens these days. A new "smart" monitoring machine can not only record second-by-second data on the slumbering volcano, it can also analyze the information and decide what to send to scientists first. During an eruption, the monitors also will give scientists more and better information from areas previously too dangerous to install equipment.
So if the volcano rumbled back to life 29 years after the devastating May 18, 1980, eruption, scientists could deploy the monitors and quickly gather all kinds of information about the event and the possible danger.
The machines, called spiders because of their stabilizing legs, are sturdier and record more information than previous machines. But the real claim to fame is that the monitors' computer-programmed "brains" can decide what some data means and which information is most important, said Rick LaHusen, an instrumentation engineer with the U.S. Geological Survey.

Scientists continue to learn from Mount St. Helens
by Michael Milstein, The Oregonian Thursday January 29, 2009, 8:31 PM
A year after Mount St. Helens ended its most recent eruption, returning to sleep for who knows how long, scientists continue learning from the volcano on the horizon. They're piecing together clues pointing to the subterranean forces that brought the volcano back to life in 2004, when it began building a gigantic new lava dome in its crater, stopping early last year.
Researchers are realizing that future eruptions also might begin with little warning. Slightly more than a week separated the first seismic signals that the mountain was reawakening and the first blasts from its crater -- far less warning than the mountain gave before the deadly 1980 eruption that made it famous.

Air-dropped deployment of a 5-station sensor network to Mout St. Helens
Sat, 10/16/2008 Renjie Huang
On Oct 15th 2008, we successfully air-dropped 5 stations into the rugged crater of Volcano St. Helens, which only took one hour with a helicopter. The stations communicate with each other through an amplified 802.15.4 radio and form a self-forming and self-healing multi-hop wireless network.The distance between stations are up to 2 km. Each sensor station collects and delivers real-time continuous seismic, infrasonic, lightning, GPS raw data and their derived data (such as RSAM) to a gateway.
