Visible Light Communications Cooperative Architecture for the Intelligent Transportation System
Résumé
This paper presents the experimental results for
a cooperative system that uses Infrastructure-to-Vehicle (I2V)
and Vehicle-to-Vehicle (V2V) communication to increases the
traffic safety, efficiency and adaptability. The wireless
communication technique chosen to enable the data transmission
is Visible Light Communication (VLC) due to its numerous
advantages. The system consists of a commercial LED-based
traffic light as a Road-Side-Unit (RSU) emitter, a transceiver that
receives the message from the traffic light and retransmits it to
the vehicle behind by using the tail lights, and also a second
receiver that receives the message from the transceiver.
Measurements exhibit a Bit Error Ratio of 10-7, both for the I2V
and V2V, without using any complex error correction codes,
which is considered good, even for traffic safety applications. The
tests results show that the proposed cooperative system allows the
RSU to communicate with vehicles outside the service area by
using multi-hop communication.
