Ensuring mobility and the necessary volume of transportation is one of the basic conditions for the functioning of the economy. The potential threat to existing transport systems is therefore an area that needs increased attention. The complexity of modern transportation is due to its increasing frequency, the expansion of transport routes, as well as the increase in the number of actors involved in their implementation, which places ever greater demands on their mutual coordination. It is necessary to constantly monitor the progress of transportation, to identify and assess the risks that may affect them. Insufficient attention to this issue can lead to time and material losses, in the worst case, the death of their participants, or to the high financial costs required to rebuild the disrupted system. Transport is an open system in which more and more people are working, whether transported or involved in its organization, which increases the possibility of their failure and facilitates the possibility of attack. Strict application of risk management, assessment and, if necessary, implementation of necessary measures can lead to protection of high-value assets. At present, we already commonly encounter concepts such as the intelligent transport route or the autonomous means of transport. All these circumstances, as well as the importance of transport, which we could compare to blood circulation of the state's economy, make it a possible target for various types of attacks. Cyber threats and attacks are becoming more and more relevant today. Such an attack is characterized by a relatively low level of threat to the attacker himself and a possible high level of damage if it is successful.

Vertical handover is one of the key technologies that will enable the connected and autonomous vehicles deployment. The emergence of vehicular networks—V2V, V2I, V2X—communications has enabled new applications, such as cooperative intelligent transport systems (C-ITS), real-time applications. However, these networks are characterized by a high level of mobility and dynamic change in the topology, which generates scattered networks. To address this problem and ensure a high level of performance, a new concept denoted heterogeneous vehicular networks (HVN) emerged, which is a key concept of the internet of vehicles (IoV). It consists in a hybridization the vehicular network (IEEE 802.11p) and cellular networks (3G/LTE/4G). In this chapter, authors introduced this new concept of IOV and its architectures and communication layers. Then they explored the different existing data relaying mechanisms in order to propose a new classification of handover approaches. After that, they presented the support of handover mechanisms in LTE and finally highlighted some handover challenges and issues.

Future intelligent transport systems depend on the accurate positioning of multipletargets in the road scene, including vehicles and all other moving or static elements. The existingself-positioning capability of individual vehicles remains insufficient. Also, bottlenecks indeveloping on-board perception systems stymie further improvements in the precision and integrityof positioning targets. Vehicle-to-everything (V2X) communication, which is fast becoming astandard component of intelligent and connected vehicles, renders new sources of informationsuch as dynamically updated high-definition (HD) maps accessible. In this paper, we propose aunified theoretical framework for multiple-target positioning by fusing multi-source heterogeneousinformation from the on-board sensors and V2X technology of vehicles. Numerical and theoreticalstudies are conducted to evaluate the performance of the framework proposed. With a low-costglobal navigation satellite system (GNSS) coupled with an initial navigation system (INS), on-boardsensors, and a normally equipped HD map, the precision of multiple-target positioning attainedcan meet the requirements of high-level automated vehicles. Meanwhile, the integrity of targetsensing is significantly improved by the sharing of sensor information and exploitation of mapdata. Furthermore, our framework is more adaptable to traffic scenarios when compared withstate-of-the-art techniques.
