DESIGN AND IMPLEMENTATION OF LOW-POWER WIRELESS COMMUNICATION SYSTEMS FOR IOT APPLICATIONS

Abstract

Due to the exponential rise in the Internet of Things (IoT), there is a growing need to have effective, and low power wireless communication systems. Their role and importance relate to their ability to facilitate the smooth communication of a large number of IoT devices without any issue in various ways such as smart homes, health care, industrial automation and environment monitoring. This study is related to the design and deployment of low-power wireless networks that are optimized in such a way as to address the distinct requirements that exist in the context of IoT spaces, where low-energy consumption, high reliability, and scale figure most prominently. A number of communication protocols and technologies under consideration are Bluetooth Low Energy (BLE), Zigbee, LoRaWAN, and NB-IoT, which is compared and contrasted in the context of power consumption, range, data rate, and network scalability. The paper also examines how energy-harvesting technology, low-power transceivers and sleep-mode approaches can be integrated to ensure that IoT networks make better use of power. Also, real deployment considerations of these systems are taken into consideration and experimental results are provided with the purpose of providing the actual performance of these systems under IoT applications. The results provide an understanding of the concerns and the way forward of creating a long-term, low-power wireless communication that would be able to facilitate the increasing number of users of the IoT networks.
