Design and implement of WSN based on Bluetooth and embedded system

Wireless Sensor Networks, WSN for short, envisions ubiquitous computing future in many fields, such as environmental monitoring, traffic management, disaster forecasting, military surveillance and inventory tracking. In this paper, we put forward the software and hardware design methods of WSN which based on Bluetooth and embedded system. We adopt the Bluetooth as the means of wireless communication, choose LPC2114 as the microcontroller, use microC/OS-II as the software platform, and take humidity and temperature sensor, microphone and photosensitive resistance as the sensor data collection modules. Aiming at the traits of small capacity wireless sensor networks, we propose and realize a rapid and concise routing algorithm based on single path. It can enhance reliability and reactive speed by simplifying the network. At last, we realize the design scheme and test the real WSN nodes.
