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 fall in the random nature of the event, and in the speed and accuracy of its notification to the authority. The pervasiveness of vehicles in the cities, and their communication and monitoring capabilities, allow 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 a VANET. It uses a cooperative-based strategy where vehicles dynamically coordinate the monitoring and dissemination of events in real time by the means of clusters. A performance comparative analysis in NS3 with a target tracking approach shows the efficiency of MINUET regarding the real-time monitoring, the dissemination of urban event data and data availability at the destination in dense and sparse networks.

重大城市事件的发生是随机发生的，需要公共当局迅速对其进行处理，以维持城市的正常运转。有效处理的主要挑战在于事件的随机性以及事件通知权威的速度和准确性。车辆在城市中的普及以及它们的通信和监视能力，使VANET能够支持此类事件的传播和处理。因此，这项工作提出了MINUET，这是一个在VANET中运行的动态系统，用于支持监视和传播城市事件。它使用基于合作伙伴的策略，其中车辆通过集群动态地实时协调事件的监视和传播。
