Problems solved by technology

However, the existing research only considered the single characteristic of the UAV, and did not solve the problem of frequent routing breaks caused by the dynamic change of the UAV height; because the single-path routing did not make full use of the effective information of the network, it increased the number of Small routing overhead, and data transmission cannot be transmitted in parallel, or cannot find a backup path in time when the link is disconnected, resulting in low network transmission rate
