N2 - In order to implement an effective directed medium access control and routing protocol in a directed ad hoc network, the node in the network should know the state of the neighboring nodes. However, it is difficult to sense signals in other directions, due to the strong directivity of the directional antenna. It will result in problems such as link collision. In order to solve the above problems, this paper proposes an orthogonal frequency division multiple access (OFDMA) based neighbor discover and tracking protocol for directional ad-hoc network. Then this paper discusses the neighboring state partitioning method based on discovery time and multiple resource unit access and frame format design based on OFDMA. The simulation results show that compared with the directional transmission and reception algorithms protocol, the protocol proposed in this paper increases the number of neighbor discovered nodes by 200$$\%$$ when the number of neighbor nodes is about 30. The nodes can connect neighbor nodes frequently, and it improves accuracy of neighbor nodes position.
