On the usability of Bluetooth in V2I based communications for extended infrastructure support

Abstract

The paper investigates the possibility to employ Bluetooth communications in a heterogeneous vehicular ad-hoc network with the purpose to improve connectivity and fast delivery of short safety, signaling or cooperative driving messages. Intensive testing has been performed in different conditions to determine if the Bluetooth technology is suitable for fast linking of moving vehicles, in different scenarios. Variable length messages have been sent and different test conditions have been assessed. Suggestions for applications of Bluetooth in V2I (Vehicle to Infrastructure) communications are also given in the paper, along with an analysis of the advantages and disadvantages of employing such a communications technology in vehicular traffic management.
