Emergency Information Dissemination in Mobile Networks for Vehicles

Due to the unacceptably high number of accidents with severe consequences, in-vehicle safety systems that provide a better service to drivers are needed. One of the key technologies for supporting the development of efficient safety systems is vehicular communication. In this paper we propose a reactive protocol for disseminating emergency notifications to vehicles in traffic. The communication performance and the protocol usefulness for help avoiding accidents are investigated via computer simulations. The results of the evaluation indicate that timely and reliable communication can be provided by the proposed protocol.
