Vehicular ad-hoc networks have been developed for set of applications that improve road safety measure, vehicle traffic coordination, and also provide comfort application. Cooperative communications that can improve the reliable communication by having a collection of radio terminals transmit signals in a cooperative way. This paper proposes a Medium Access Control (MAC) in cooperative scheme, called Cooperative Ad-Hoc MAC (CAH-MAC). Due to a poor channel condition the neighboring nodes cooperate by utilize unreserved time slot for retransmission of a packet which fails to reach a target receiver in CAH-MAC.
