Abstract
MAC protocol design is an important task for safety message broadcasting in VANETs. Previous research works have solved many basic problems. They have a poor performance in the high dynamic and dense vehicle environment. This paper proposes a slotted and OFDM federated protocol in which the control channel of IEEE 1609.4 is divided into many sub-channels for all nodes in the network to avoid conflicts and improve packet delivery ratio. Simulation results show that the proposed protocol has a higher performance of packet delivery ratio.
