CCH, The current Medium Access Control (MAC) protocol of the Wireless Access in Vehicular Environments (WAVE) system does not consider time utilization of and SCH. In this paper, we present a novel mechanism to extend MAC protocol, which dynamically adjusts the length of Control Channel (CCH) and density, Service Channel (SCH) intervals according to vehicle and load conditions of network. In the proposed mechanism, each vehicle makes use of the beacons to evaluate reception probability in CCH then adjusts duration of CCH interval accordingly. This enables vehicles to handle traffic load conditions and reliable, provides and applications., efficient data transmission for safety applications to ensure human safety while maintaining time for non-safety
