Traffic Analysis of LEO Satellite Internet of Things

The Internet of Things (IoT) is a burgeoning paradigm that changes our lives greatly. In many cases, IoT devices are located in remote areas, which can't be served by terrestrial access networks. As a consequence, Low Earth Orbit (LEO) satellite communication system may play an important evolution of 5G, and becomes of paramount importance for those scenes relying on its disadvantages. Additionally, the first integration of terrestrial communication and satellite communication in 5G also provides more technical support for the 5G system. Based on the analysis of the special application scenarios and traffic distribution characteristics of LEO satellite based IoT, this paper describes a simulation method for the traffic of LEO satellite based IoT. The simulation result shows that the distribution of business in LEO satellite system has great suddenness and variability both in time and space. Since the non-uniformity is not conducive to the stability of the system, it is necessary to guide the construction of LEO satellite based IoTs according to the distribution characteristics and laws of the business.
