GPS-Less Localization System in Vehicular Networks Using Dedicated Short Range Communication

摘要

Vehicular localization plays an important role to enable safety and traffic flow control in intelligent transportation systems (ITS). Global positioning system (GPS) is generally used to localize a vehicle, but it is challenging to obtain the accurate location when the GPS signal is blocked from the satellites or corrupted by the multipath propagation. In this work, we present a GPS-less localization system using dedicated short range communication (DSRC). The primary objective is to accurately localize a vehicle without GPS. To this end, we propose a localization scheme using infrastructure-to-vehicle (I2V) and vehicle-to-vehicle (V2V) communications.
