Integration of space and ground collaboration based on near space platform

In this paper, we firstly propose the concept of aerostat cluster in the space and ground integration network. Then we discuss the structure of the near space aerostat network based on the business requirements of communication. After that, we design the routing algorithm (named ISPR) in near space network and make an in-depth analysis. Lastly, we propose an access method (named G_AAT) to achieve the address translation from ground network to near space network. Based on the work, we design a new communication mode (peer to peer communication in space network, named Air_PP), which realizes the purpose of integrated communication between space and ground. The simulation results show that our routing algorithm is flexible. By using Air_PP, the ground network is easy to access the space network. What's more, the robustness of the network is good.
