Location Verification based on Radio Irregularity: Sequential Evaluation and Performance Assessment

Abstract

In this paper Location Verification System based on Radio Irregularity and Sequential Evaluation (LVS-RISE) is proposed as a novel system to improve the performance of the Location Verification System based on Radio Irregularity (LVS-RI). LVS-RISE utilizes a sliding window and voting scheme to detect the attack from malicious nodes at the same distance. Hence, LVS-RISE can limit the ambiguity of malicious nodes detection when compared with LVS-RI. To assess the performance of LVS-RISE in compared with LVS-RI both simulation and experimental results are presented. Our simulation results show that, with the same threshold of detection, LVS-RISE achieves better performance when compared with LVS-RI. Moreover, the experiments in real environment indicate that an assistant node is necessary for LVS-RI and LVS-RISE if the node to be detected is moving.
