Abstract

Recent advances in wireless communication technologies and the emergence of computationally rich vehicles are pushing VANETS. VANETS is an approach to provide road safety vehicle traffic management. Cooperative communication links in VANETS is mitigating wireless channel because of user mobility. In this paper we present medium access control for Adhoc in cooperation scheme known as cooperative Adhoc Mac. In CAH-MAC the cooperative nodes are supported for retransmission the packets from source to destination. The helper node is used when the retransmission of packets is failed to reach the destination. So through analytical results we show the throughput is increasing in CAH-MAC and packets are successfully reach the destination.
