Airborne networks (ANs) are always faced with the challenge of anti-jamming communications due to a lack of physical boundaries. A robust decentralized routing (RDR) protocol is proposed in this paper for ANs with directional antennas in the content of the network layer. The routing centrality is first defined and its correlation with the network topology is investigated. Accordingly, a novel weight assignment mechanism is proposed to make the central node less often appear on a routing path. In this way, the failure rate of routing can be decreased once the central node is disconnected. Based on simulation results, the routing centrality of the central node can be reduced from 39.6% to 21.8% while the average end-to-end delay (EED) is slightly increased.
