A RFID Based Localization Algorithm Applying Trilateration for Wireless Sensor Networks

Abstract

The localization technology takes an important role in real-time alarm and rapid response. In this paper, we propose a novel localization method for wireless sensor networks, which is based on Radio Frequency Identification technology (RBLOCA). This method combines above both techniques and achieves the localization in WSN. The method not only has the advantages of real-time monitoring and low cost of WSN, but also has the characteristics of fast and repeatable use of RFID technology. Experimental results show that the proposed method can achieve a higher positioning accuracy. At the same time, the energy consumption of nodes is also very low. Therefore, we can get the method has a wide range of applications in a number of scenarios such as the forest fire alarm system, underwater sensor network.
