Abstract: A medium access control (MAC) protocol was proposed based on Reliable Reservation ALOHA (RRALOHA) in order to meet requirements of the multivehicle cooperative system for realtime, reliability and distributed property. The realtime capability of intervehicle communication was enhanced through dynamic time division multiple access (TDMA). The reliability and distributed property were enhanced through timeslot reservation and efficient broadcast mechanism. On this basis, multivehicle cooperation algorithms were designed based on intelligent vehicles, and cooperation scenes were implemented including platoon and overtaking. The experimental results proved the feasibility and reliability of the intervehicle communication protocol presented.
