Multiple Hybrid Strategies Filtrate Localization Based on FM for Wireless Sensor Networks

Abstract

Aiming at the malicious attack problem in FM positioning, based on the characteristics of FM broadcast signal, a kind of FM Multiple hybrid Strategy Filtrate Localization (FMFL) is proposed: according to the current FM signal characteristics, the reasonable distance error range of each anchor node is determined, which is effective. The effect of joint attack and other methods on the performance of the positioning algorithm is reduced. At the same time, in order to improve the positioning accuracy of the algorithm more effectively, the positioning process is divided into two stages: anchor node validity verification and positioning calculation. The experimental results show that this method can obtain higher security and positioning accuracy in the presence of multiple malicious attacks.
