Abstract
Aiming at the demands of low cost,low consumed energy and accurate localization in wireless sensor network, a novel method of using radio interference and Doppler shift for localization is proposed in this paper. One mobile anchor node moves on two intersecting lines,generating a Doppler shift,and another anchor node is stationary. Radio waves emitted from two anchor nodes create the radio interference field. The unknown nodes measure variations of instantaneous frequencies of their own radio interference signals to obtain the necessary ranging information for localization. Simulation demonstrates that the method can achieve desired performance with high accuracy. At the same time,with simple algorithm and low computation cost, the method is especially applicable to locate a number of nodes distributed in a broad area.关键词
