# Intelligence-Based Strategies with Vehicle-to-Everything Network: A Review
## 2 Background
### V2X Technologies
Nevertheless, total avoidance of collisions is unattainable due to concurrent channel selection. Traditional cellular networks can facilitate unicast,broadcast, and multicast connections. Nevertheless, the substantial messaging latency associated with these setups renders them unsuitable for transmitting CAM messages. To cater to the requirements of transportation systems, the 3 GPP started the standardization process for the LTE-V specification in Release 14 [3; 22; 23]. This standardization is intended to facilitate V2P, vehicle-to-V2I, and vehicle-to-V2V services, collectively called V2X services. The standard has devised a novel channel model utilizing the PC5 interfacing to accommodate automotive networking demands. Additionally, the standard supports the traditional unique user interface for various transportation applications [3]. Release 12 of the LTE standard, used for public safety, saw the development of the sidelink, which enables D2D connectivity and is a component of the PC5 link. V2X communication capabilities are undergoing enhancements in LTE Release 15 and are scheduled to receive additional improvements in Release 16 [23]. A revolutionary foundation for transforming mobility and automotive systems is created when 5G technology is coupled with Internet of Vehicles (IoV) technologies. Enabling VANET communication is made ideal by this synergy, which enables low-latency, ultra-reliable, and smooth connection with extraordinarily high bandwidth. 5G improves the security, efficiency of traffic, and user experience in IoV networks by allowing fast data transmission and real-time connectivity across infrastructure, cloud systems, and automobiles. Combining this with fog/edge computing helps to address one of the major problems with the Internet of Things (IoT): processing data in real time from different locations. Fog/edge computing, in contrast to conventional, centralized cloud systems, moves processing capacity towards the source of data, which in this case is automobiles and roadside infrastructure. Applications such as autonomous driving, collision avoidance, and adaptive traffic management rely on this closeness to drastically decrease latency. This also reduces bandwidth usage by performing analysis close to the source, reducing the quantity of unprocessed information transferred to main servers. The Internet of Vehicles

Cellular networks, including LTE and 5G, offer multiple benefits compared to DSRC. These include increased bandwidth, wider service area, and better data transmission rates. Nevertheless, cellular networks exhibit certain limitations in comparison to DSRC technology. The following are provided below:  
* V2X communication in DSRC is a decentralized communication that operates directly between peers without requiring any involvement from a network administrator. However, the cellular network demands assistance from a network provider. * In a cellular network, information is transmitted via the uplink and downlink lines to reach where it is supposed to go. However, in DSRC, information may be immediately conveyed to the endpoints without any intermediate steps. * The cellular system requires network access to function. However, DSRC can transmit information anywhere by simply broadcasting it over airspace. * DSRC is significantly more cost-effective than the cellular network. * DSRC is solely for V2X communication, in contrast to cellular networks which share bandwidth among competitors' users.
