  Critical urban events take places at a random way and they need to be dealt
with by public authorities quickly to maintain the proper operation of cities.
The main challenges for an efficient handling of an event fall precisely in its
random nature, and in the speed and accuracy of the notification of its
manifestation to the authority. The pervasiveness of vehicles in urban
environments, and their communication and monitoring capabilities, allow to
employ VANETs to support the dissemination and handling of such events. Thus,
this work proposes MINUET, a dynamic system to support the monitoring and
dissemination of urban events, which operates in an ad hoc vehicular network.
It uses a cooperative-based strategy where vehicles are able to dynamically
coordinate the monitoring and dissemination of events in real time by the means
of clusters. Results obtained by NS3 show the performance of MINUET regarding
the real-time monitoring and dissemination of events detected in urban areas.
