The Design of Wireless Sensor Network Localization System Based on Arduino

Abstract

Wireless sensor network is a new network project, whose rapid progress improves the ability of people to obtain natural information, which makes the human society more convenient. And it combines the collection of physical information data and the transmission of wireless network, and has a very excellent application prospects. The capability of node localization in wireless sensor networks is also the fundamental of its application and research. Different kinds of positioning technologies have been studied, especially for low power consumption, low cost, easy to realize and so on.

In this paper, we study the localization technology of wireless sensor network based on Arduino, that is to obtain the accurate location of the object through the wireless network, and realize the positioning function. Firstly, the research background and current research status of wireless sensor network, secondly elaborated the localization technology of wireless sensor networks, then introduces RSSI ranging principle, then according to the RSSI localization model study, according to the indoor environment, the establishment of corresponding RSSI localization model, system to achieve the function, hardware and software design, at last, using the Arduino platform verify RSSI positioning model. The test results show that the design scheme of this topic is feasible.
