Traffic management solutions.
| Solution | Principe | Disadvantages |
|---|---|---|
| Broadcasting-based [29] | Broadcasting of messages. | Risk of congestion of circulating messages. |
| Route discovery-based [30] | Learn about the state of traffic on an arc before accessing it | Response time is relatively large |
| Position-based [31] | Method based on the position of each vehicle and the intersections to be traveled to reach its final destination. These intersections are determined either by street-maps or by V2X communication protocols. | Each two vehicles must maintain communication between them which generates a large number of exchanged messages that can slow down the operation of the protocol. |
| Cluster-based [32] | Vehicles on the same arc and having identical properties form a cluster. Each cluster communicates with neighboring clusters and thus has a global view of traffic in the environment | Security issues related to identification, privacy, integrity ... |
| Infrastructure-based | The protocols where vehicles communicate with each other, but also with infrastructures (RSU for example) | The cost of infrastructure is generally high, and no party is easily convinced to invest in it. |
