In April 2011, we launched the CitySee system as the extention of GreenOrbs into urban CO2 monitoring area. CitySee inherits the self-organizing WSN technology of GreenOrbs. The goal of CitySee is to deploy thousands of wireless sensor nodes in an urban area of Wuxi City, China, such that multi-dimensional data including CO2, temperature, humidity, light, location, and etc. could be collected in a real-time manner for further analysis. The main applications of CitySee include measuring the carbon absorbance and emissions in different zones of a city, supporting the government’s policy decision in energy saving and emission reduction, and offer citizens with convenient daily living services.



 The missions of GreenOrbs are two fold:

On one hand, GreenOrbs realizes all-year ecological surveillance in the forest, collecting various sensory data including temperature, humidity, illumination, and carbon dioxide titer. The collected information is utilized to support various significant applications, such as forest surveillance, forestry observation and research, fire risk evaluation, and succor in the wild.

On the other hand, GreenOrbs pioneers the effort in the sensor network community to build a practical system. Through the real-world experience in GreenOrbs, we expect to explore the potential design space and scientific solutions, especially addressing the research and engineering challenges for a wireless sensor network system that is deployed in the virgin forest, involves 1000+ sensor nodes, and needs to operate for over one year.



                                   SecureR FID                                      


 RFID (Radio Frequency Identification) is an important enabling technology for logistics and supply chain management systems. The amount RFID devices will continue to leap in coming years. It was predicted that China will need at least 4.5 billion RFID devices in 2008, and 5.5 billion in 2010. At present, there are well over 100 RFID vendors and enterprises inChina.

Despite enormous propaganda on RFID and its great potential, large-scale deployment of the trust-enabled RFID technology is still uncommon. There is an immediate need to further advance the trustworthy technology of RFID before its benefits can truly be realized in Logistics and Supply Chain Management (LSCM). Challenging problems have been raised by the industry on security and privacy. Solutions to these problems will bring major impacts on the popular deployment of the RFID technology, which is a core area of logistics and supply chain management.

Our team is dedicated to developing a set of trustworthy RFID methodologies and critical technologies to exploit the emerging opportunities.



                                   Ocean Sense                                      


OceanSense aims to build an integrated sensor network system for environment surveillance on  the sea. The focus of this work is to acquire and analyze information about environment factors such as temperature, light illuminance, sea depth, etc. Current methods are mostly labour-intensive and the data collection lacks both the density and consistency of samplings. By deploying a wireless sensor network, we are able to achieve continuous surveillance on the sea environment.

We are deploying the working system in Tsingtao, China. We use TelosB motes and TinyOS as our development basis. Current system consists of 20 sensor nodes deployed in the field, reporting sensing data continuously to the base station. The complete system is designed to scale to hundreds of  sensors covering the sea area off Taipingjiao, Tsingtao.
