摘要：Vehicular ADHOC 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 ADHOC 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. In this paper, we present a dedicated short range communication which performs the faster packet transmission. Through mathematical analysis and simulation, we show that reliable communication of CAH-MAC by decreasing PDR and hence increasing throughput performance in different networking scenarios.
