  Abstract

In this paper, we propose a novel TDMA-based MAC protocol for reliably transmitting safety messages in vehicle ad hoc networks. The MAC protocol of IEEE 802.11p, which is the current V2X communication standard, has a problem in that packet loss increases rapidly when large numbers of messages occur within a dense environment. The existing TDMA studies proposed to solve this problem tend to have a large overhead for scheduling. The proposed TDMA protocol can reduce such an overhead, solve the hidden node problem, and even share the advantages of CSMA based approaches. The proposed algorithm is designed to select slots by exchanging slot state information and to access media after detecting the carrier in the selected slot. We have confirmed through a NS-3 simulation study that the packet reception rate and channel usage of the proposed scheme is greater compared to the existing protocol.
