Abstract :
Vehicle to vehicle (V2V) communication is regarded as an important means to avoid traffic accidents and improve vehicle safety. The reliability of the V2V communication strongly depends on propagation issues such as propagation loss determined by node distance, fast fading by multipath propagation, and hidden terminal problem when multiple vehicles exist. However, analysis of the packet delivery rate considering hidden terminals in fading environment has not been sufficiently investigated. This paper presents the method for analyzing the broadcast packet delivery rate of V2V communication by setting a mathematical model considering CSMA/CA mechanism. The obtained results show that the number and the position of interfering vehicles, as well as carrier sense level, significantly affect the packet delivery rate.
