The works of [3] and [4] present proposals for monitoring
and detection of traffic conditions, using V2V (Vehicleto-
Vehicle) communication. To accomplish this, beacon-type
messages are transmitted. Such messages are simple, have
low overhead and are used to announce the presence of a
vehicle to its neighbors. Other approaches, such as ConProVa
[5] use only V2I (Vehicle-to-Infrastructure) communication,
which limits the proposal. In ConProVa, mechanisms to deal
with issues relating to the provision of contexts in vehicular
networks are implemented in the infrastructure. For this, Con-
ProVa implements a middleware in order to assist in decision
making and resolution of conflicts of interest regarding the
actual traffic situation reported by vehicles, since vehicles
cannot collaboratively validate conditions detected on the road.
