With the increase of the number of connected vehicles on roads, the data dissemination within traditional network suffers from many limitations like high latency, a significant amount of dropped packets and network congestion. Therefore, the Internet of vehicles (IoV) has been designed as an emerging paradigm that combines the intelligent transportation system (ITS) with Internet of Things (IoT) technology. IoV allows vehicles to exchange data with its surroundings in order to enhance the traffic safety and to provide digital services to road users. In this paper, a taxonomy of data dissemination protocols proposed for IoV is surveyed according to three main categories namely, the smart control‐based category, social networks‐based category, and traditional approaches. We also review the data dissemination in IoV based on the fifth generation (5G) communications with emphasis on enabling technologies, architectures, services, and challenges. Moreover, we suggest in this study a new generic 5G‐based IoV architecture named IoVs based on fifth generation communications to enhance data dissemination by the promising and efficient transmission technologies such as fifth‐generation network properties, software‐defined network functionalities (SDN), and cloud‐fog computing services. The proposed scheme helps to meet challenges in the low latency, high reliability and security, high performance, mobility contrary to conventional architectures.
