Koucheryavy, The Bonch-Bruevich State University of Telecommunication, head of department, Dr. <...> This paper presents the impact of intentional electromagnetic interference on the functioning of wireless sensor networks. <...> As a result of such influence, there is degradation of channel quality among nodes, leading to destruction, distortion and blocking of the transmitted information. <...> Consequently, this results in disruption of connection among nodes and disruption of the network structure due to failure of nodes. <...> The methods for increasing the probability of network operation using adaptive routing based on parameter quality of service and using supernode, which allow multiple reserves for coordinator/gateway of wireless sensor network. <...> The obtained results can be used for solving the tasks of increasing the probability of data delivery in wireless sensor networks under intentional electromagnetic interference conditions. <...> INTRODUCTION At the present time development of the Internet of Things (IoT) has a significant impact not only on the development of communication networks, but also on the image of our humanity [1, 2]. <...> Wireless sensor network (WSN) is a distributed network consists of many miniature sensor nodes, which carrying out the control, monitoring and data 32 acquisition. <...> Great interest to the study of such networks is caused mostly by wide possibilities of their application: meteorological data (temperature, pressure), telemedicine, emergencies (fires, accidents, etc.), military operations (positioning of moving ЭЛЕКТРОСВЯЗЬ |3| 2017 ЦИФРОВАЯ ОБРАБОТКА СИГНАЛОВ Figure 1 Ultrashort electromagnetic impulse targets, territorial spread of chemical weapons) and others <...>
