# Smart Handoff Technique for Internet of Vehicles Communication using Dynamic Edge-Backup Node
###### Abstract  
A vehicular adhoc network (VANET) recently emerged in the the Internet of Vehicles (IoV); it involves the computational processing of moving vehicles. Nowadays, IoV has turned into an interesting field of research as vehicles can be equipped with processors, sensors, and communication devices. IoV gives rise to handoff, which involves changing the connection points during the online communication session. This presents a major challenge for which many standardized solutions are recommended. Although there are various proposed techniques and methods to support seamless handover procedure in IoV, there are still some open research issues, such as unavoidable packet loss rate and latency. On the other hand, the emerged concept of edge mobile computing has gained crucial attention by researchers that could help in reducing computational complexities and decreasing communication delay. Hence, this paper specifically studies the handoff challenges in cluster based handoff using new concept of dynamic edge-backup node. The outcomes are evaluated and contrasted with the network mobility method, our proposed technique, and other cluster-based technologies. The results show that coherence in communication during the handoff method can be upgraded, enhanced, and improved utilizing the proposed technique.

The V2V communication system provides a 360-degree view of similarly-equipped vehicles within communication range. Vehicle control information includes the transmission state, brake status, the steering wheel angle, and the vehicle's path history with path prediction. Another computational need in vehicular communication is providing a direct information exchange, single-hop and multi-hop method of communication. This type of exchanged information could substantially reduce the volume of accidents (by exchange hazard awareness messages) and time of travel, extended driving vision, and help others in making their drives more comfortable. In contrast, within V2I the information exchanged in a bi-directional packet communication and there is a high bandwidth link between the vehicle and roadside equipment that needs to be additionally provided to maintain a communication between vehicle and roadside unit. The work in [2] has listed the following four applications of VANET. 1. Commercial orientation gives entertainment and services to the drivers. 2. Safety orientation monitors the surrounding road. 3. Convenience orientation deals with traffic management to enhance or upgrade traffic efficiency. 4. Internet connectivity, as shown in Figure 1, is required to provide uninterrupted provision of the above three services. In order to form an IoV-enabled technology, vehicles should be interconnected efficiently with less linkage breakdown probability. In achieving this, a robust handoff mechanism needs to be properly involved. Accordingly, handling such a process, the handoff algorithm is normally implemented to manage the procedure. The aim of the handoff management is to maintain the active connections when a mobile node (MN) changes its point of connection. This handoff management involves computational process and overview image of the wider scope of the mobility cluster that with conventional vehicular communication will not be visible. Hence, recently the concept of mobile-edge computing (MEC) has shifted most of the processing overhead from the end mobile device to the edge-server that is physically closer to the MN and provides very low latency and prompts responses for the computational tasks. Hence, utilizing this concept for IoV could achieve a tremendous benefit out of MEC. To accomplish the handoff in the IoV networks, the handoff system is directed to be effective in assigning and reassigning the IP addresses.
