Analysis of handshake time for bluetooth communications to be implemented in vehicular environments

The key element in modern Intelligent Transport Systems is the communication between all the devices, as neither of them can run independently, but require interaction with other equipment. This is also true for vehicles: advances in autonomous vehicles field requires communications with other vehicles or infrastructure, in order for the vehicle to be aware of its environment. There are several technologies available for short/medium distance that are suitable for vehicular communications. The most used one for vehicle-to-vehicle is Dedicated Short Range Communication. However, in many applications this expensive technology is not necessary, especially when the key element is connection time, due to the reduced data quantity needed to be exchanged. In this paper we have performed analysis on Bluetooth, as the most common short distance communication technology, and we have tested the handshake time in noisy Wi-Fi environments.
