This paper proposed an MAC (Media Access Control) operation method based on the CCH (Control Channel) and SCH (Service Channel) control mode of the WAVE (Wireless Access for Vehicle Environment) network in order to secure service performance sensitive to certain delays with no restriction to services pursued in the present WAVE network. The proposed method configures a new superframe for CCH and SCH frames in the WAVE network defined by IEEE Std. 1609.4 and applies TDM (Time Division Multiplexing) to the CCH frame in order to secure traffic stability and latency minimization in each terminal. CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance) is applied to the SCH frame in order to secure autonomy in service perspectives. Additionally, delay control is secured despite congestion among multiple terminals in V2V communication without a station RSU (Road Side Unit) since the proposed MAC operation method adopts a new CCH/SCH coordination mode for the WAVE network. The proposed method’s applicability is verified as the simulation analysis results showed satisfactory low latency performance.
