Heterogeneous LTE/Wi-Fi architecture for ITS traffic control and infotainment

Intelligent Transportation Systems (ITS) make use of advanced technologies to enhance road safety and to improve traffic efficiency. In order to assist passengers to travel safely, efficiently and conveniently, several application requirements have to be met simultaneously. For this purpose, this paper proposes a heterogeneous LTE/Wi-Fi vehicular system that supports both infotainment and ITS traffic control data. A performance simulation-based study is conducted to validate the feasibility of the proposed system in an urban vehicular environment. The system performance is evaluated in terms of data loss, data rate, delay and jitter. The results indicate that the proposed system offers acceptable performance that meets the requirements of both infotainment and traffic control.
