Research on UAV Cluster Routing Strategy Based on Distributed SDN

Abstract

UAV clusters are able to strike targets flexibly in military operations, but the traditional routing cannot support multiple routing tables. In this paper, we present a routing strategy under multistage flow table based on distributed SDN architecture, which is more efficient for the combination and separation of UAVs. According to the characteristics of channels, we can schedule the mechanism and preset the priority. The distributed strategy does not have centralized controller, which can avoid network congestion and achieve higher reliability. The experimental platform of distributed interoperable data distribution with twenty nodes is established. The results show that this routing strategy is better than the traditional routing mode in terms of end-to-end delay and throughput.
