ABSTRACT
It is very common to rule out Bluetooth as a suitable technology for vehicular communications. The reasons behind this decision usually result from misconceptions such as accepting that Bluetooth has a short application range, or assuming its connection setup is not fast enough to allow communication which involves high speed moving nodes. This paper refutes those assertions and proposes the use of Bluetooth not only for Infrastructure-to-Vehicle (I2V) or Road-to-Vehicle (R2V) communications, but also for Vehicle-to-Vehicle (V2V) or Vehicle-to-Infrastructure (V2I) communications. This novel proposal is based on using the remote name request procedure of the standard, combined with an adjustment and optimization of the parameters present in the inquiry and page procedures. The proposed modifications reduce the information exchange delay, thus making Bluetooth a suitable technology for high-speed vehicle communications. The feasibility of the proposed scheme has been validated through experimental tests conducted in different scenarios: laboratory, a real highway and a racing test circuit. There, the communication system was installed in a vehicle circulating at speeds of up to 250 km/h, whereas autonomous devices were disseminated throughout the road path to communicate with the on board devices obtaining satisfying results.

sensors-15-12765-f014: Received RSSI in a real highway.

Mentions: Regarding connection times, i.e., the addition of the time spent in the inquiry procedure and the remote name request, are similar to the obtained in the speed circuit, around 200 ms. The main difference observed when comparing Figure 11 and Figure 14 is the increase of the coverage. With this configuration, it is possible to receive a remote name request up to two kilometres away from the fixed equipment. This enhancement is due to the higher position of the fixed equipment which improves the propagation conditions. If the fixed equipment is placed at the height of a road sign (2–3 m) the range is reduced to around 700 m.
