With the development of unmanned aerial vehicle (UAV), the air-ground collaborative communication network which composed of UAV and ground base stations has also been developed and innovated. It can improve the performance of a delay tolerant network (DTN) consisted by a single network node. In this paper, we conduct a comprehensive evaluation and analysis of the performance of DTN air-ground cooperative networking through various features, such as UAV's the movement mode, movement speed, node cache, message survival time, network node density, routing protocol and others. The results show that the addition of UAV relay nodes can effectively improve the information transmission efficiency of DTN. In the scenario of large-scale node air-ground cooperative networking, air-ground cooperative networking is suitable for time-sensitive services and can improve the message delivery rate by 75% in a low message survival time.
