Development of a simulation model of an 802.16 wireless broadband access network using Network simulation 2 (NS-2)
Introduction: the paper considers the process of developing a simulation model of wireless broadband access of the 802.16 standard using Network Simulation 2. This approach allows you to quickly build the required network model using the OTcl scripting language without having to delve into the structure of the compiled part of ns-2. If modification or addition of the compiled part is necessary, this can be done by adding (or changing) the C++ code and recompiling the system. The only drawback of this approach is the difficulties in studying the system and debugging programs (models) arising from the use of two languages. The purpose of the study: In the work using the NS-2 simulator, it was necessary to identify the capabilities of various wireless broadband access standards, to conduct both analysis and comparison. Results: In order to realize the purpose of the study, a simulation modeling process was carried out. Based on the experiment, a decrease in packet loss and delay time was revealed when using the 802.16 standard. compared to other wireless broadband access standards. Practical significance: the use of this model in the design of wireless networks makes it possible to increase the efficiency of data transmission. Discussion: As a further study, a detailed consideration of the impact of modern data transmission protocols using a simulation model is required.
