Vehicular Ad hoc network(VANET) disseminates traffic data by providing self-organizing decentralized environments, the public interest of traffic data makes it appropriate for VANET data dissemination methods to rely on broadcasting. However, when data is broadcast under high density scenarios, the issues of scalability and data distribution redundancy which can lead to broadcast storm become even more pronounced. Aiming at the issues of data transmission redundancy and broadcast overhead, based on the farthest forwarding strategy and piggybacked acknowledgment mechanism, this paper proposed an adaptive most forward within radius based on piggybacked acknowledgement(AckAMFR), which transmitted and stored information according to the concept of store-and-forward. AckAMFR can reduce the data redundancy and it also has strong reliability and small broadcast costs. Simulation results show that the forwarding strategy has the characteristics of low broadcast overhead and high data rate.
