The paper investigates existing methods for optimizing energy consumption in IEEE 802.15.4 Internet of Things protocols.The following protocols were considered: ZigBee, 6LoWPAN, and WirelessHART.The ZigBee protocol has a sleep mode, frequency response control, transmitter power management, data aggregation and buffering, and transmission route optimization.6LoWPAN uses sleep mode, frequency response control, IPv6 header compression, fragmentation and reassembly, and transmission route optimization.The WirelessHART protocol uses sleep and activation mode, frequency mesh, transmitter power management, data buffering and aggregation, transmission route optimization, and network topology management.The study selected the criteria by which all optimization methods in IoT protocols are distributed: Device activity time management, Transmission frequency characteristics management, Transmitter power management, Data packet management, and Route management.The ZigBee and Wireless HART protocols have optimization methods for all the proposed categories.The 6LoWPAN protocol has 4 categories of optimization methods, except for the Transmitter Power Management category.The best energy efficiency indicators are found in the optimization methods of "Device activity time management" and "Route management."This is because devices are turned off when data is not needed to collect and transmit.Since devices can send data from other devices to the data center, the routing setting eliminates unnecessary data transfers and leaves the device in sleep mode longer instead of waiting for data from other devices to be sent.The worst-performing methods are those in the Transmission frequency management category because they are based on detecting transmissions that create collisions.Still, devices are in sleep mode most of the time, and their transmissions rarely overlap, so collisions are rare.
