Performance Analysis of LTE Smartphones-Based Vehicle-to-Infrastrcuture Communication

With an increase in number of vehicles on road, applications and services offered by Intelligent Transportation System are growing in demand. However, there are still coverage and capacity limitation of wireless links that support such services. In this work, we address a new and novel concept that leverages 4G network for vehicle-to-infrastructure communications. Instead of considering on-board units communication interface, we make a case for using smart-phones as economical alternative given that an interface exists between vehicle navigation system and smart phone. The applications considered in this paper are broadband internet access and entertainment applications (video streaming etc.) We provide performance analysis results using LTE-simulator. Our high-level conclusion is that smart phones enriched with LTE capabilities are feasible for vehicular communications given that fourth generation network penetrates market rapidly.
