Abstract:
Abstract: Considering the demand that traffic accident information needs to be broadcasted with high- efficiency
and low- latency,this paper proposed a novel multi- hop transmission scheme based on fountain codes for inter- ve-
hicular safety information transmission,and theoretically analyzed the optimal transmission hop number. Through a-
dopting the fountain broadcast transmission and selecting proper relay vehicle according to the optimal transmission
hop number,the efficiency of safety information broadcast transmission can be improved and the transmission delay
can be decreased obviously. Moreover,the fountain scheme for inter- vehicular information transmission was simula-
ted where vehicle location distribution is followed to exponential function and the relay vehicle was selected accord-
ing to the principle of nearest position to the optimal relay vehicle location in theory. The simulation results demon-
strated that the theory analysis was correct and practical communication performance was improved obviously
through the scheme.
