Cooperative Monitoring and Dissemination of Urban Events Supported by Dynamic Clustering of Vehicles

Abstract

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.
