IoT Research Topics: The Internet of Things (IoT) is the network of physical objects—devices, vehicles, buildings, and other items embedded with electronics, software, sensors, and network connectivity—that enables these objects to collect and exchange data. Here things are uniquely identifiable nodes, primarily sensors that communicate without human interaction using IP connectivity. In this article, ilovephd provides more than 100 high-impact IoT Research Topics and Projects you can consider in the year 2025

A thing in IoT can be anything with sensors and internet connections. (Wrist Watch, Sunglass, TV, Car-Key, etc.) All these devices collect and store an enormous amount of data from every person.

Once data is collected, all the data from IoT devices are transferred to data analysis, as a result of this process some useful in-depth personal recommendations will be generated also which will lead to a smart and efficient life.
