Abstract

Daily urban critical events demand correct actions by the responsible authorities. Thus, information from these events should be efficiently disseminated to the competent entities. VANETs can naturally support the monitoring of random events in time and space. In addition, social relationships between vehicle users establish local communities whose social intelligence can be applied to disseminate data collected by VANET to support public management in event recognition. This work investigates how social parameters influence the quality of data dissemination of urban critical events. We analyzed the impact of social influence, social activity and friendship strategies, and also consider the tradeoff on QoS and QoE. Results show that social activity brings a more significant influence on QoS, with an increase of 106% to 175% in the packet delivery than the others in dense environment. Further, social influence performs better on QoE subjective metrics, delivering packets with an excellent quality level.
