Abstract
A Cooperative Intelligent Transport System (C-ITS) is a system where mobile stations OBU (On-Board Units) exchange messages with other ITSS-V (Intelligent Transport System Station Vehicle) or RSU (Road Side Units). Messages are sent through a specific WIFI (IEEE 802.11p) denoted also ETSI ITS-G5. The efficiency of this technology has been proven in terms of latency. However, RSU are common everywhere and stations equipped with G5 interface are not widely deployed. For this reason we look for another mean to guarantee this communication. Bluetooth Low Energy (BLE) is deployed on smartphones. We take advantage of this deployment to propose an architecture based on this protocol in order to build a Cooperative Intelligent Transport System. Cellular networks are widely deployed and can support these communications. We have adapted the ITS stack provided by the ETSI (designed for G5) to the BLE protocol.
