 is key for this paradigm where in many operations human intervention will be eliminated. The network elements working cooperatively need to be able to also protect the infrastructure, the information, the use of the cloud, and the privacy of the users. Even service providers need to work cooperatively in order to achieve such adaptability, intelligence, and automation. Edge computing will assist in the resource sharing tasks and the communication and delivery of the information necessary for control of the network. New network paradigms where IoV, VANETs, and B5G work together are being proposed; see [51]. The challenges are many, and IoV is evolving and needs help to propose solutions to those challenges. In [51], some of the issues that we have mentioned are addressed, such as scalability, but from the perspective of a reliable delivery of information through an optimized way of sharing resources for vehicles. A discussion is also included about modern multiple access techniques for vehicles using beacons, connectivity of the vehicular network is analyzed, and convenient deployment of RSU within a network planning methodology is presented. Challenges also evolve as technology does, and new smart techniques need to be developed in order to cope with new problems that arise with new communica- tions services and technologies. Smart communications will help create a logical infrastructure where solutions can be developed that will permeate technologies, 7 Vehicular Communications in the B5G Era paradigms, and problems finding optimized ways of communicating information across digital platforms such as those on ground mobile, aerial, or fixed networks. 7.6 Conclusions Vehicular communications are one of the key elements in order to provide frame- works for the adoption of intelligent transportation systems, particularly for the case of connected and autonomous vehicles. The capabilities foreseen in current 5G systems and future B5G/6G systems enable wider range of V2X communication links, providing higher reliabil
