Title   Wireless Sensor Network node Self-positioning System Design

Abstract

Wireless sensor network as a new information acquisition and processing technology, has a great application value and scientific value in defense, industry and agriculture, environmental monitoring and other fields. Because large numbers of the applications of wireless sensor network are based on the location information of network nodes, so the node positioning technology is the one of the key technologies.

All kinds of the components which are used in this system are firstly introduced in this paper, expounded the hardware conditioning circuit which is put the cylindrical polar body microphone as acoustic sensors. Then the connection between MSP430 and NRF24L01 is introduced in detail. On this basis, the paper also describes programming of wireless nodes based on the software platform of IAR FOR MSP430,enabling wireless communication between nodes. Finally, complete serial communication with the PC through the MSP430 microcontroller connection node and, to achieve a real-time display. In this paper, demonstrate the accuracy and stability of the test system with a large number of experiments and testing, and thus achieve the wireless sensor nodes self-positioning technology.

Keywords: Wireless sensor networks  the node positioning  IAR  MSP430
