USRP Devices Application for Modeling Signal-Like Interference in Wireless Networks

The object of consideration is wireless networks of the 802.11 standard, also modeling options for the intruder active impact on the physical environment to evaluate the effectiveness of information interaction in the presence of signal-like interference. The subject of the study is the development of software and hardware solutions based on the USRP architecture and LabVIEW software environment for modeling the intruder active impact at the physical level, aimed at destroying or reducing the information interaction effectiveness of wireless network clients. The purpose of the study is to substantiate the possibility and evaluate the effectiveness of the USRP devices and LabVIEW software environment for prototyping specialized hardware and software devices use. The solutions are based on the documented characteristics of National Instruments Corporation's USRP devices, a description of LabVIEW virtual devices that solve particular problems of physical monitoring, but mainly on the results of authors experimental studies, as well as testing these results and technical solutions in the educational process. The article is devoted to substantiating the relevance of modeling an aggressive electromagnetic environment, building specialized software and hardware devices based on the USRP architecture, testing a number of scenarios for generating signal-like interference with an evaluation of their effectiveness.
