Novikov V. A method of increasing the throughput of mobile wireless sensor networks based on the use of telecommunication aerial platforms

The dissertation solves an important scientific and technical problem - the development of a method of increasing the bandwidth of mobile wireless sensor networks based on the use of telecommunication air platforms. The main scientific and practical results of the dissertation are as follows. The mathematical model for estimating the connectivity of mobile wireless sensor network nodes with telecommunication air platforms has been improved. The essence of improving the model, which determines its novelty, is that the proposed methods of joint use of a set of analytical models for assessing the reliability of data transmission in radio channels with a set of analytical models for predicting the movement of mobile sensor nodes. This allowed not only to assess the availability of connectivity according to the specified reliability, but also to predict its duration in the conditions of rapid and unpredictable movement of mobile sensor nodes. The algorithm for finding the quasi-optimal position of telecommunication air platforms has been improved. The essence of the improvement of the algorithm, which determines its novelty, is that this algorithm has avoided a complete overhaul of telecommunications airplanes by using a pre-designed set of rules for selecting options for such a change in network connectivity, which reduces computation time. This allows you to get real-time close to optimal solutions and use the algorithm to quickly control the position of telecommunications aircraft platforms. The deviation of quasi-optimal solutions from the optimal ones obtained by the method of complete search does not exceed 5-7%. For the first time a method of increasing the bandwidth of mobile wireless sensor networks based on the use of telecommunication air platforms was developed. The difference between the developed method and the known one, which determines its novelty, is that for the first time it is proposed to combine into a single system a computational procedure for analyzing a mathematical model for estimating structural and functional connectivity of mobile sensor nodes and an improved quasi-optimal positioning algorithm achieve close to extreme bandwidth values ​​of mobile wireless sensor networks in the conditions of fast and unpredictable movement of mobile sensor nodes.
