Toroshanko O. Methods for improving routing efficiency and measurement accuracy in wireless sensor networks with mobile agents

Object of research - the process of analysis and management of parameters and condition of wireless sensor networks of general and special purpose. The subject of research - models and methods of development of the distributed sensor network with the increased efficiency of routing, accuracy of measurements of resource and energy saving. Research methods. In the dissertation methods of the theory of probabilities and mathematical statistics, the theory of networks, the theory of filtration Kalman - Bussey, modeling and calculations on the computer were applied. Theoretical and practical results: the method of controlled directional diffusion with mobile agents was developed for the first time. Unlike previously used methods, the theory of controlled random processes is applied here, due to which the sensitivity of sensory detection / measurement devices to losses and distortions of a priori information is reduced, and, as a result, to the influence of false signals; For the first time, methods of combined searchless estimation and detection algorithms for spatial segments of the sensor network, physical access to which is limited or impossible due to the fact that they are in inaccessible places, have been developed. The new methods differ from the existing ones in that they take into account statistical differences in the processes of sensor drift and the evolution of the measured parameters, due to which the required accuracy of determination is achieved with sufficient simplicity of implementation; improved model of distributed multilevel data collection system based on a complex wireless sensor network with controlled logical topology using radio communication channels, which allowed to provide general coordination of local hardware and software subsystems in real time.
