In designing MAC protocols of Unmanned Aerial Vehicle Ad Hoc Networks（UANET）

control overheads and delay of data transmission have to be considered. Based on the existing multi-hop TDMA protocol of wireless Ad Hoc networks and the characteristics of UANET

an efficient and low delay multi-hop TDMA protocol of UANET is proposed. Our proposed method can reduce the network control overhead by efficient broadcasting using time slot allocation information based on topology information. It can also reduce the average network latency and improve success rate by the one hop node secondary allocation of data time slot and the multi-dimensional scheduling node time slot allocation sequence. The simulation results show that the proposed protocol outperforms the existing UAV MAC protocols when UAV nodes move faster and the topology changes frequently in terms of message average delay
