  Abstract

This paper studies a resolution to the hidden node problem in the WAVE. In order to apply the idea of the virtual carrier sense, we focus on two characteristics of broadcast-based safety services in WAVE. First, the emergence safety message is more critical to vehicles approaching the emergency spot among broadcast receivers. Second, through periodic exchange of basic safety messages, each vehicle is constantly aware of locations of neighboring vehicles. Utilizing those characteristics, this paper proposes selective RTS/CTS handshake as an effective method against the hidden node problem in WAVE. In addition, a method of supplementing the selective RTS/CTS handshake in dealing with the synchronized collisions inherent in WAVE’s multi-channel switching operation, is also presented. Through experiments performed in the multi-channel switching environment, it was confirmed that the purpose of the study could be satisfactorily realized.
