The most important goal in transportation systems is to reduce the dramatically high number of accidents and fatal consequences. One of the most important factors that would make it possible to reach this goal is the design of effective broadcast protocols. In this paper we present an emergency broadcast protocol designed for sensor inter-vehicle communications and based in geographical routing. Sensors installed in cars continuously gather important information and in any emergency detection will raise the need for immediate broadcast. The highway is divided in virtual cells, which moves as the vehicles moves. The cell members choose a Cell Reflector that will behave for a certain time interval as a Base Station that will handle the emergency messages coming from members of the same Cell, or close members from Neighbor Cells. Besides that the Cell Reflector serves as an intermediate node in the routing of emergency messages coming from its neighbor Cell Reflectors and does a prioritization of all messages in order to decide which will be the first to be forwarded. After this the message will be forwarded through the other Cell Reflectors. Finally the destination Cell Reflector will send the message to the destination node. Our simulation results show that our proposed protocol is more effective compared to existing inter-vehicles protocols.
