Communication Solutions for Vehicle Ad-hoc Network in Smart Cities Environment: A Comprehensive Survey

摘要

In recent years, the explosive growth of multimedia applications and services has required further improvements in mobile systems to meet transfer speed requirements. Mobile Ad-hoc Network was formed in the 1970s. It is a set of mobile devices that have self-configuring capable to establish parameters to transmit data without relying on an pre-installed infrastructure systems. Today, MANET is strongly applied in many fields such as healthcare, military, smart agriculture, and disaster prevention. In the transportation area, in order to meet the unique characteristics of the vehicle network, such as movement pattern, high mobility with the support of RSUs, MANET has evolved into Vehicle Ad-hoc Networks, also called VANET. Due to the mobility of the nodes, like MANET, the performance of VANET is relatively low and depends on the communication technologies. Designing more flexible, reliable, and smarter routing protocols to improve VANET performance for smart urban is a significant challenge. In this study, we conduct a survey of communication solutions for VANET in recent years. The results indicated a common framework for designing VANET communication solutions based on three main approaches: multi-metric, UAV/Cloud/Internet, and Intelligent. Moreover, with each proposed solution, we also analyse to show the focus of the research and the results achieved. Finally, we discuss and point out possible future research directions. We hope that the research results in this work will be important guidelines for future research in the communication area for VANET.
