The invention provides an enhanced neighbor information-based multi-hop broadcast protocol (ENIMBP) in a highway scene. A optimal transmitting vehicle is selected by combining neighbor information of vehicles with positions, steering speeds and directions of the vehicles to determine transmitting
waiting time. According to the positions of the vehicles, the ENIMBP can initially determine the transmitting
waiting time of the vehicles different in distance from a broadcast vehicle. Under the condition of same distance between the vehicles and the broadcast vehicle, the ENIMBP differentiates the transmitting
waiting time by means of speeds and directions of the vehicles. The ENIMBP solves the network partitioning problem and node hiding / exposing problem in the highway scene.
Simulation results show that the end-to-end
delay can be remarkably reduced in a sparse network, and meanwhile, a very high
packet arrival rate is maintained. As the speeds and directions of the vehicles are introduced, the transmitting waiting time of the vehicles with same distance can be differentiated, and under the scene of great vehicle density, the high
packet arrival rate can be further maintained.
