In this research, a power consumption analysis of wireless devices for Internet of Things applications is described. The research analyzes and contrasts a variety of tiny wireless communication techniques and their modules, including ZigBee, Energy Saver Wi-Fi, Six-Low-PAN, and LPWA, all of which aim to conserve energy and lengthen the lifespan of the devices that make up an IoT network. This focuses on the significance of employing small wireless techniques and components in IoT applications. The study s methodology is defined by the individual module used to implement the protocol. According to the degree of communication between sensor nodes, the proposed protocols are categorized. ZigBee, 6LoWPAN, and low power Wi-Fi are the candidate protocols for connectivity over short distances. The LoRaWAN protocol is a possibility for long-distance connectivity. Given the wide variation in power consumption between modules and protocols, the results of this study demonstrate how carefully selecting units for every protocol can greatly affect the duration of its use. Accordingly, protocols are compared with one another in various ways based on the module in question.
