The performance measurement of various wireless links is done using a simulator, emulator, or in real-time focusing on a variety of major performance parameters of the wireless links. Satellite links are one of the most widely used communication mediums for long-distance communication whose performance affects the overall performance of the heterogeneous networks. The simulation is the first step in performance evaluation which gives a synthetic environment with most of the things programmed and controlled which generally is unlike the real-time scenario. On the contrary, real-time testing has a constraint of availability, as well as, it is very difficult to arrange and control parameters in real-time. Whereas, the emulation provides a more realistic environment compared to the simulator by involving realistic hardware and links as well as allows the incorporation of performance parameters and network dynamics to see its real-time effects on packets being transferred. The research article focuses on emulating LEO, MEO, and GEO satellite links to study the effect of the performance parameters in run-time during actual communication. An in-depth analysis of the results and plots is carried out to understand the quality measures of satellite communication. The work concludes that the emulation results have higher similarity to real-time testing compared to simulation environment. Also, delay latency, file size and other link constraints affects the performance and hence they play an important role in deciding overall performance of data transfer.
