INCREASING THE LEVEL OF INFORMATION SECURITY IN WIRELESS SENSOR NETWORKS BY IMPROVING THEIR GEOMETRIC MODELS

ABSTRACT

The geometric models of wireless sensor networks are analysed. The selection conditions of an optimal network model are proposed. To improve information security measures, the visualization method of changing the signals parameters with consideration of the number of information nodes and their location in space is developed. The development and advanced use of wireless sensor networks require constant improvement of their reliability, durability, and performance as well as a high level of information security. The above characteristics significantly reduce the threats that cause unauthorized changes of signals parameters of information nodes. Arrangement of conditions for visual observing the signals parameters of information nodes is one of the most important means of improving the reliability and efficiency of wireless sensor networks. Geometric model networks in Euclidean configuration space are considered an effective tool for organizing such observations. The geometric models of wireless sensor networks should be developed according to the recommendations on the quantity and quality factors of information nodes, in particular their location in space.
