Abstract
Safety applications have been popular research topics in recent years, such as forward collision warning, emergency electronic brake lights and intersection collision warning. The basic safety message is used to broadcast from each car that transmits the position, car speed and car heading information. Neighbourhood cars receiving this information can decide on the danger or not in the next second. However, the safety application message has a time-critical problem. The reliable and efficient delivery of safety information needs to improve when the penetration rate increases. Many research works focus on two angles: one is the control of transmission power, and the other is the control of transmission frequency. This paper proposes a novel concept to reduce the broadcast message method in vehicular networks. The proposed method will not change the transmission power and transmission frequency, but reduces the repeat and derivable information between the broadcast messages.Keywords
