Abstract

The paper considers the energy efficiency problems of IoT systems when using power supplies of limited capacity. Such power sources include batteries and disposable batteries. The small amount of energy in the power supply of IoT devices requires additional time to design a system that will interact with IoT devices. With proper design, a person will be less likely to interfere with the system to replace the power supply. In the Internet of Things, devices that are sensors or controllers are connected by a single network. This system is used to improve the living conditions of man, and should work without human intervention. In such systems, power supplies should allow IoT devices to operate for several years without replacing the power supply. When designing an IoT system, it is necessary to perform an analysis of data exchange protocols to select the optimal ones to work in the system. Protocols can be divided into two categories: signaling protocols and data structure protocols. Signal transmission protocols determine the data transmission medium, frequency characteristics of signals, data encoding methods, the structure of data packets. Data structure protocols define a method of describing data to quickly separate some data from others during processing. To select protocols, you must define the data that will be transmitted over the network. Next, analyze the data types. Based on the analysis, determine the optimal data structure protocol. Then you need to determine the signal transmission protocol. It must rely on the data structure protocol, as its data will be transmitted in the IoT system. You can view the baud rate and coverage radius. High-speed protocols deplete the power supply faster. If there is no need for high speed, then such protocols can be discarded immediately. There may be situations where several protocols will give the same results. In this case, system developers must decide which one to use.
