Abstract
The subject of the study is the wireless sensor network of the ZigBee protocol, which in this study is proposed for performing the function of measuring the distance between objects. The main areas of application are security facilities, such as warehouses, shops, exhibitions and expositions, where it is important to control the movement of valuables in a limited area with a large concentration of people. The sensors are made on a flexible basis, attach to valuable objects and all the time transfer information about the distance relative to each other. One of the most problematic places is the limited bandwidth of data transmission channels. Also, for the above-described rooms are all kinds of obstacles, like mechanical (walls, partitions, metal shelves), and radio interference, for example, wireless network interfaces of buyers' phones and others. The study used a method to improve the performance of wireless sensor networks within computerized distance measurement systems based on the decomposition of the lower levels of the OSI reference model. The same capacity indicators as for analogues were obtained, but the load that the network node sustained was 2.5 times higher. This is due to the fact that the proposed method of increasing productivity, has a number of features that improve performance characteristics, in particular in areas of uncertain reception almost twice. Thanks to this, it is possible to operate the network at a maximum speed of 32.5 Mbps. Compared to analogs in which the maximum speed is 12.5 Mbps this provides more accurate results of distance measurement. Also, thanks to this speed reserve, the best noise immunity is provided, as well as the ability to locate network nodes at distances that are greater than those of analogues.
Highlights
The timely determination of the position of an object included in the wireless sensor networks results in the generation of false information in a computerized system for measuring the distance between objects
Among the various classes of computer information systems and networks, a special place is occupied by systems and networks whose transport service is based on the use of radio ester as a data transmission medium for computerized distance measuring systems [2]
Develop an algorithm for functional alignment of nel device will be proposed. This process will be considered improve the performance of wireless sensor networks in with some inaccuracy, since it is presented as stationary, areas of uncertain reception and to investigate the effect without taking into account transient processes
