The complex operational environment makes the network topology and channel environment complex and volatile, which brings challenges to the maintenance of aeronautical network connectivity. In order to satisfy the demand for network connectivity of aeronautical network, a dynamic relaying protocol based on status information for aeronautical network is proposed, and Exata network emulator is used to analyze the performance of the proposed protocol. By comparing the throughput performance between two aeronautical platform away from each other in three kinds of the aeronautical network without relaying, with fixed relaying, and with the proposed relaying protocol, the use of the proposed protocol can achieve better performance of the network throughput, which means that the proposed protocol is good in maintaining the aeronautical network connectivity.
