Energy efficient method of data transmission in a heterogeneous network of the Internet of things for remote areas
The paper reviewed and analyzed protocols, technologies for transferring and presenting IoT data, developed a model of a heterogeneous IoT network for hard-to-reach areas, proposed a method to improve the efficiency of data transfer in a heterogeneous IoT network. As a result of the work, a model of using the Internet of Things technology (LPWAN) in hard-to-reach areas was developed, information presentation methods were identified that allow solving the problem of collecting information from remote sensors located in the absence of traditional communication channels and a practical check of the results obtained. The paper uses simulation modeling to study the applicability of different methods of presenting information in the case of transmitting IoT data over low-speed satellite communications channels. The method proposed in the paper allowed the use of the Internet of things technology in remote areas using the SBD satellite short message service. The proposed method allowed reducing the volume and number of SBD messages during data transmission via low-speed satellite communication channels, which made it possible to reduce the cost of communication data transmission by 4.82 times.
