An important task in the design of a system for determining the location of mobile objects is to assess the effectiveness of its functioning, since the use of these systems inside premises for managing production processes, ensuring security or logistics, in modern conditions, is one of the digital economy’s paramount goals. This scientific work is dedicated to the characteristics of a ZigBee technology sensor network, which is the basis for a local positioning system. The ultimate goal of the study is to build an effective hardware and software complex for indoor geolocation. As a research tool, the authors have chosen an analytical modeling method using the mathematical apparatus of closed queuing networks, which is the most suitable for obtaining the quality of service indicators of telecommunication networks. The time-probability characteristics, which are the quality of service indicators in a geolocation system based on the IEEE 802.15.4 (ZigBee) standard equipment, were obtained in the course of modeling. The aforementioned results make it possible to manage the traffic of the existing or planned sensor network effectively. |
