An Emergency Message Propagation System Using Roadside Units and Vehicle-To-Vehicle Communication

摘要

This paper presents a message propagation system that uses Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication. In emergency situations, wireless technology enables vehicles to share warning messages with other vehicles using V2V and with emergency services by using V2I. The time that passes before an emergency service is notified about an emergency situation, such as an accident, is critical. In this paper we evaluate the effects of traffic density, V2V adoption rates, the number of hops for messages in V2V communication, location and number of roadside units on the performance of message propagation for emergency response and network coverage.
