TinyOS
TinyOS is an open-source operating system designed for wireless embedded sensor networks. It features a component-based architecture which enables rapid innovation and implementation while minimizing code size as required by the severe memory constraints inherent in sensor networks.
I am a developer of TinyOS project group on Sourceforge.net and have the commit rights to its CVS.

XMesh
The XMesh protocol stack is an open-architecture, flexible, and powerful embedded wireless networking and control platform built on top of the TinyOS operating system. XMesh combines proven high-performance with interoperability thru the support of open standards including IEEE 802.15.4/ZigBee.
I've participated in the project of new XMesh2 for its design and performance evaluation.

XFactory
XFactory is a general manufacturing test framework for wireless products. This framework include a series of testing firmware for every Crossbow wireless hardware, to evaluate their performance under normal & extreme conditions. This framework also provides a generic GUI shell that can be customized for a particular test using a custom GUI plug-in and test firmware.
I was in charge of this project, work together with our hardware engineers.

MOTE-VIEW
MOTE-VIEW was designed to be the primary user interface between a user and a deployed network of wireless sensors. It provides an easy means of logging wireless sensor data to a database, analyzing, and plotting sensor readings. Sensor data can be logged on a database resident on a host PC, or to a database running autonomously on a Stargate gateway.
I've taken part in the development of its visualization module.

Data Fusion System for Sensor Network
Data fusion system can deal with different kind of sensor information from multi sensors, and combin them together to reach a more accurate result. Data fusion is very useful in large-scale, low-power wireless sensor network.
As the team Leader, I'm responsible for the data fusion and the target tracking algorithm; and I also take part in the sensor network simulation system.

Wireless Sensor Network for High Voltage Power Grid
The safety of high voltage power grid is extremely important. With the lattest wireless communciation technology, we can sit down and monitor its status at real-time.
We brought a revolutionary idea at that time, by using the SMS of cellphone network for sensor data acquisition, each embeded cellphone was a wireless mote.

Supervisor Control And Data Acquisition System(SCADA) for Transformer Substation
SCADA is a sensory system for gathering and analyzing real time data. SCADA systems are widely used to monitor and control the transformer substation and power system.
This project is the topic of my graduate thesis. As the team Leader, I've designed a strong, extensible software architecture and implemented its major functions.
