You can explore the technologies for the development of efficient and reliable communication infrastructure to support IoT devices in smart cities like IEEE 802.11ah (Wi-Fi HaLow), LPWAN (Low-Power Wide-Area Networks), cloud, and edge computing for enhancing connectivity.

You can explore different data management techniques for collecting, processing, and analyzing vast amounts of data generated by IoT devices in smart cities.

You can explore traffic management, and mobility solutions using IoT technologies like smart parking, congestion management, connected vehicle networks, etc.

Daer Rajwinder Kaur,

I would suggest a topic for your research integrating SD-IoT (Software Defined Internet of Things) and the idea of “Digital Twins in IoT”.

Some of my figures can provide ideas for the use of SD-IoT and Digital Twins in Smart Sities. See for this:
