“…In [26], a performance analysis of data dissemination protocols applied to VANETs is carried out, where events are place at different locations in the test scenario. The impact of using different radio propagation models to disseminate emergency messages is investigated in [27]. In [28] a performance analysis to disseminate safety and non-safety messages in VANETs based on the fog paradigm is presented.…”

The treatment of mobile and simultaneous critical urban events requires effective actions by the appropriate authorities. Additionally it implies communication challenges in the speed and accuracy of their occurrence by the entities, as well as dealing with the dynamics and speed in these environments. Cooperative solutions with shared resources that address these challenges become a real option in helping to handle these events. This paper presents an evaluation of dynamic monitoring and collaborative dissemination supported by vehicular groups. It aims to analyze the impact of multiple mobile and fixed events in an urban environment on information propagation, considering barriers imposed by the events and the environment. Differently from other studies in the literature, this work takes into account both fixed and mobile events, as well as simultaneous events. NS3 results show that the evaluated system monitored at least 87% and 51.5% of the time for mobile and fixed events respectively, and delivered information over 77% and 50% of the time for those events, with average delay remains close to 0.3s in most scenarios. The results also reveal that a more continuous monitoring of the mobile events is highly dependent on the orientation of the vehicles. The main contribution of this work consists of the performance analysis of both fixed and mobile simultaneous events to support studies on how moving events impact on the dissemination and delivery of real-time data, and thus encouraging the development of new data dissemination protocols for VANETs.
