Performance Analysis of V2V Beaconing Using LTE in Direct Mode With Full Duplex Radios

Vehicles will soon be equipped with wireless communication systems enabling a variety of new services. At the basis of each service is the transmission of beacon messages that advertise the vehicle's presence. In this letter, we investigate long term evolution (LTE) as the enabling technology for vehicle to vehicle (V2V) beaconing by exploiting: 1) the direct device to device (D2D) communication provided by Release 12 of LTE; and 2) the full duplex (FD) radio, which allows a wireless device to transmit and receive at the same time. Furthermore, we introduce a novel analytical framework to evaluate the resource occupation of the beaconing service in LTE and compare the results with those obtained using LTE for vehicle to infrastructure (V2I) communications.
