Abstract

These days, smart city is an emerging concept, and every government is planning to make their cities smart. Smart cities integrate ICTs in almost all aspects of daily life. These technologies provide better performance at affordable costs to improve quality of life and deliver interaction between such sources. Internet of Things (IoT) is one of the most emerging technologies to be deployed for smart cities. These days, IoT is applicable in virtually every side of life, such as roads, health, lights, waste management, buildings, transportation, and other aspects of IoT to change the verge of development in every element of smart cities. Objective: To secure the environment, IoT devices are very vital in different technologies. This paper is aimed to discuss various recent trends and applications of IoT in smart cities and deployment in real world. Methodology: To fulfill these objectives, this study is based on secondary data collected from various relevant studies and online sources. Findings: The IoT devices use sensors that are connected to Bluetooth, Wi-Fi, and RFID for data collection. These connected devices make the world smarter and evolves smart environment as smart cities, smart buildings, and smart homes. These services are improving transportation and infrastructure systems, providing waste management, minimizing traffic congestion, and improving quality of life of citizens to transform cities.
