Temporal Link Signature Measurements for Location Distinction

摘要: We investigate location distinction, the ability of a receiver to determine when transmitter has changed location, which application for energy conservation in wireless sensor networks, physical security radio-tagged objects, and network detection replication attacks. In this paper, we using measured temporal link signature uniquely identify between (TX) (RX). When TX changes or if an attacker at different assumes identity TX, proposed distinction algorithm reliably detects change channel. This can be performed single RX collaboratively by multiple receivers. use 9,000 signatures recorded locations over time demonstrate that our method significantly increases rate reduces false alarm rate, comparison existing methods. present procedure estimate mutual information Edgeworth approximation. For data set, show approximately 66 bits is contained each signature.
