Modeling of Data Traffic in Space-Air-Ground-Integrated-Network with Cellular-Connected Remotely Piloted Air Systems

Using Space-Air-Ground Integrated Network (SAGIN) for data transmission requires reliable two-way communication. This work is devoted to the development of theoretical methods for predicting the functioning of SAGIN. The issues of integration existing space, air and ground networks for efficient interaction during heavy traffic and the choice of data transmission modes to ensure the required Quality of Service (QoS) are the main topic of this study. Original models were created for simulation data traffic in SAGIN. Models included Base Station (BS), LEO satellite, low-altitude Remotely Piloted Air Systems (RPASs) connected with Cellular Users (CUs) and were designed using NetCracker Professional 4.1 software. The dependences of the uplink Average Load on the size of transactions for a different number of network users were obtained. The effects of different bandwidths and Bit Error Rate (BER) were studied.
