VANET Communication Range Degradation: An Experimental Study on the Ole of Interference 2.0

Abstract

In vehicle-to-vehicle (V2V) communications, the communication range degradation has been associated with high channel load. In particular, interference has been avowed to play a moderating role, suggesting that at higher distances, the likelihood of packet loss could not be overstated. It is also notable that at least two concurrent transmissions account for the packet loss, especially due to collisions that occur at receivers that come in between. The latter outcome transforms into a hidden station problem. The aim of this simulation study was to conduct a real-world experiment and discern the percentage of degradation in the communication range due to the aforementioned complexities. The study involves three radio stations, which aided in gaining data about interference and how it could cause communication range degradation. Results demonstrated that the degradation was between 50 and 70%. The number of collisions was also found to increase due to the shadowing effect of the receiving vehicle, having hidden other stations even in situations where distances were closer.
