Sensorweb is also called Internet of Things. If Internet is viewed as the circulatory system connecting the world, then Sensorweb can be said as the nervous system sensing the world: extracting timely information for efficient decision support and quick corrective actions. MIT Technology Review listed it as one of the top ten emerging technologies in 21st century that will change the world.

We are currently developing Sensorweb systems for environment monitoring, smart environments and smart grid applications, where sensing, computing, communication and control play a critical role and need a transformative study. Those technologies will directly contribute to the sustainability of our society by improving  environment safety, healthcare effectiveness and energy efficiency

 

Active Research Projects:

This project creates a real-time Ambient Noise Seismic Imaging system, to study and monitor the subsurface sustainability and potential hazards of geological structures. The techniques developed find further utility in monitoring and understanding the dynamics of subsurface oil, mine and geothermal resources, alongside concomitant hazards in oil exploration, mining, hydrothermal eruption, and volcanic eruption).  ...

Cyber-security of smart grid has raised significant interest amongst both general public and researchers. However, the corresponding education programs fall behind in many aspects. Very limited curriculum or hands-on learning resources are available for security education in smart grid, especially for the mutual impacts between cyber and physical systems

We will create a new paradigm, VolcanoSRI (Volcano Seismic Realtime Imaging), for imaging 4D (four-dimensional) tomography of an active volcano in real-time. VolcanoSRI is a large-scale sensor network of low-cost geophysical stations that analyzes seismic signals and computes real-time, full-scale, three-dimensional fluid dynamics of the volcano conduit system within the active network ...

This research investigates key aspects of a computation and information foundation for future cyber-physical energy systems - the smart grids. The overall project objective is to support high penetrations of renewable energy sources, community based micro-grids, and the widespread use of electric cars and smart appliances. ...

Smart environment with prevasive sensors has a goal of automating control of home appliances in order to achieve comfort, security, energy efficiency, and recently for health monitoring of older adults or people with cognitive and physical impairments ...

In a challenged sensor network, a predictable and stable path may never exist, the network connectivity is intermittent, and a node could suddenly appear or disappear. The rare upload opportunity and unpredictable node disruptions often result in data loss. The unpredictable network disruptions make the traditional communication protocols inefficient and require a new design paradigm ...

Completed Research Projects:

 

Renewable energy sources (such as solar panels and wind turbine) will be widely installed around local communities to supplement alternative energies of power grid. It will eventually enable energy independence of our living environments ...

The promise of wireless sensor networks can only be fully realized when the wiring for both data communications and power supply is eliminated. Fortunately, energy harvesting from environment becomes more and more practical ...

The world never stops changing and evolving as time slips. Living in such a volatile and information-explosive world, it is important to keep ourselves updated ...

TelosW is a new generation wireless mote with wake-on capability. Instead of CPU activate sensors and radios for sensing or transceiving, the sensors and radios will wake on CPU ...

It is well known that designing, testing and debugging sensor networks are extremely hard. It is mainly due to limited resources and distributed natures of sensor networks...

Structures like buildings, bridges, dams, roads, nuclear power furnace, etc. are critical components of the economic and industrial infrastructure. However, these structures are aging with years and are also subjected to harsh loading scenarios and severe environmental conditions ...

Earth scientists seek to understand the complex, time-varying dynamics of volcanic activity, both for deeper scientific understanding of the physical processes, as well as to enable rapid detection of volcanic hazards to human safety...
