Location Verification Systems Based on Received Signal Strength With Unknown Transmit Power
—In the context of location verification systems
(LVSs), this work proves that knowledge of a legitimate user’s
transmit power has no effect on the optimal performance of
an RSS-based LVS. Specifically, we prove that the detection
performance of a generalized likelihood ratio test (GLRT), where
the unknown transmit power is estimated, is identical to that of a
differential likelihood ratio test (D-LRT). Our analysis also proves
the asymptotic optimality of D-LRT for an RSS-based LVS with
unknown transmit power. These results are important for realworld
deployments of LVSs, since D-LRT incurs a significantly
lower implementation cost relative to GLRT.ARC Discovery Projects Grant DP150103905
