OpenWSN, an layer first component architecture and package for sensor networks

Most of the current WSN research platforms are based on Mica nodes and TinyOS. However, it´s difficult to be integrated with the obsolete mature source code and difficult to port to other platforms. The micro-controller based solution is also weak to take high performance tasks such as image processing. So we develope an ARM7 based powerful WSN research platform named OpenWSN. OpenWSN adopts layer- first component based architecture. The hierachical feature makes it much easier to port to other hardware platforms. And OpenWSN introduces object oriented design and C language for implementation, which can make full use of the current mature source codes and human resources to lower the cost of future developing. Some more techniques are also introduced such as static resource allocation and service based policy to increase its robustness for real application. In general, OpenWSN is an appropriate solution for both industry and academia.
