Sokolov V. Methods and Means of Enhancing Information and Functional Security of Wireless Data Networks

The dissertation is devoted to the actual scientific and practical problem of de-veloping methods for guaranteeing the reliability and functional safety of wireless infrastructure on based on hardware division of subscribers to increase its level of protection against security threats of diverse nature consisting of the developed theoretical foundations, methods, models and means of reliable wireless systems and networks. The dissertation proposes methods of modified rectangular quadrature ampli-tude modulation to reduce the mutual influence of wireless networks, adaptive se-lection of free transmission channels in wireless networks using spectrum analyzers, increase of functional security in wireless infrastructure and a comprehensive as-sessment of the state of its protection systems against the anthropogenic effects. Experimental studies of the current state of wireless technologies, the mutual influ-ence of wireless networks, the efficiency of miniature spectrum analyzers and the efficiency of the accelerating lens for multiprocessing systems, as well as its dim-ming and polarization properties have been carried out. New models of spectrum analyzers, free channel monitoring system, accelerating lens antenna for multipro-cessing systems have been developed.
