Efficient event dissemination using bluetooth protocol

Abstract

A C-ITS is a system where mobile stations OBU (On-Board Units) exchange messages with other ITSS-V 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, for this reason we look for another mean to guarantee this communication. Cellular networks are widely deployed and ma support these communications. In this paper, we present an architecture which ensures communication between RSUs and mobile stations using Bluetooth protocol. We have measured some indicators as latency (notification delay), packet delivery ratio (number of messages arrived after a threshold). These indicators confirmed that our proposed architecture has a interesting performances and could be deployed widely.
