Приводятся результаты исследования зависимости скорости передачи данных (ПД) от параметров маршрута в беспроводной сети интернета вещей. Предложен метод выбора количества и позиций узлов для организации маршрута в сети. Метод учитывает влияние расстояния между узлами маршрута и их количества на задержку доставки данных и скорость ПД по маршруту. Метод позволяет получить выигрыш в достижимой скорости ПД по сравнению с методами выбора маршрута по критерию количества транзитных узлов. The article presents theresults ofthe studyof thedependence of the data transfer rate on the route parameters in wireless Internet of Things (loT) networks. A method for choosing the number and positions of nodes for organizing a route in the loT network is proposed. The method takes into account the influence of the distance between the nodes of the route and their number on the delay in data delivery and the speed of data transmission along the route. The method allows one to obtain a gain in the attainable data transfer rate in comparison with methods of choosing a route based on the criterion of the number of transit nodes.

ABSTRACTThe first prototype of high-density ferroelectric data storage system based on scanning nonlinear dielectric microscopy was developed in order to establish basic elemental technologies for actual read/write functions aiming for practical application. Using this system, a data transfer rate was evaluated. 9 kbps reading and 50 kbps writing were demonstrated with respect to 440 kbit/inch bit data array written on a lithium tantalate single crystal thin plate. Additionally, we considered future prospects for developing the data storage system with further fast data transfer rate.

Summary For the purpose of exploration and extraction, the drilling process in the mining and oil and gas industries is very complicated because of the obvious invisibility of the operation of the drill bit. Acoustic/vibrational telemetry has been of keen interest because it is so far the only method that allows a high data transfer rate as well as less data loss, over other methods. The method certainly depends on the use of the right communication tools and efficient communication schemes to achieve the highest data transfer rate. Although the acoustic method provides a very high data transmission rate, it also has its limitations. However, limitations can be overcome through certain approaches and the use of technologies. The proper use of a communication device with the steel pipe is the most important factor to consider so that the transducer works as the right actuator for the pipeline. The type of sensor that is used to pick up the data also plays a major role because signals are most likely to attenuate, and a sensitive sensor is necessary to collect these attenuated signals. This research demonstrates the use of a transducer as a communication device and oil and gas pipe as the medium of data transmission. The transducer can be used both as an actuator driver and as a receiver sensor. A new piezoelectric transducer was manufactured for this research, which was used with a test setup of a total 184 ft length of six oil and gas pipes. The test setup performed well and data were sent through this setup successfully. A communication scheme is developed using novel theories to achieve the highest data transfer rate. The scheme is tested with the transfer function data obtained from the experimental system. The communication scheme developed outputs a signal, which is a type of binary phase-shift keying signal data along with an equalizer filter. Then the signals developed from the scheme are used in the actual experimental setup to test the speed of the transmission and bit error rate (BER). For the six oil and gas pipes setup, the scheme provides a data transmission of 153 bits/sec (bps) with zero error percentage, which is high enough to use in any oil and gas industry.

The data transfer rate is the traditional criterion for evaluating the overall performance of a hard disk. In this paper, the data transmission performance of hard disk was characterized based on fractal theory. The traditional mechanical hard disks and solid state disks with different capacities and specifications were tested and the corresponding signal graph of data transfer was analysed for the calculation of fractal dimension D. The results indicate that the process of hard disk data transfer has fractal characteristics; the fractal dimension D increases with the increase of the average transfer rate and the rotating speed of mechanical hard disk. However, there seems no direct correspondence between the fractal dimension D and the capacity of the hard disk; the larger the floating range of data transmission, the greater value of fractal dimension D.
