Spoofer-to-Target Association in Multi-Spoofer Multi-Target Scenario for Stealthy GPS Spoofing

Global navigation satellite system (GNSS) based is omnipresent in today's world, providing position, velocity, and time (PVT) information with inexpensive GPS receivers. These receivers are highly vulnerable to intentional interference like spoofing meaconing. The of a single receiver using spoofer setup widespread, the concept multiple targets distributed spoofers also equally adaptable. Traditionally, spoofers, surveillance region work independently without knowing other being installed. Multiple deployment its management optimal for misguiding given surveillance. This paper presents generalized mathematical model multi-spoofer multi-target (MSMT) scenario, management, spoofer-to-target association. received power spoofed signals considered as an evaluating parameter locking onto Three novel centralized networking-based techniques proposed overcome association networking. Firstly, global nearest neighbor (GNN) proposed. overall cost function minimized by assigning unique spoofer-ID target-ID. In GNN-based spoofing, minimizes, but it does not ensure that every target-to-spoofer assignment minimum. Secondly, opportunity-based GNN resolve increase hit ratio. However, hard install more spoofers; therefore, tunable transmitting power-based presented accomplish efficient higher hit-ratio. efficiency evaluated association, ratio, position root mean square error (PRMSE). All algorithms outperform spoofing. We observe solution MSMT scenario.
