Internet of Vehicles (IoV): A Survey of Challenges and Solutions

The technological revolution of the Internet of Things (IoT) increased the number of objects (e.g., vehicles) connected to the Internet, making our lives easier, safer, and smarter. Putting IoT objects on the wheel has created a new technology called the Internet of Vehicle (IoV). The massive progress in communication and computing concepts brought the IoV to real implementation. The IoV is the advanced version of Vehicular Ad hoc Network (VANET), mainly designed to provide safe driving. Although the number of vehicles connected to the IoV keeps growing, there are various challenges and opportunities of the IoV technology that are still not clear. In this paper, several research papers related to the IoV were examined to identify and categorize the existing challenges of implementing and employing IoV in urban cities. Furthermore, this work outlines the IoV technical limitations that must be addressed. Moreover, various existing and future solutions that tackle the identified challenges were briefly discussed.
