 With the increasing demand for energy in urban areas, IoT technologies can play a crucial role in optimizing energy consumption of electricity, thermal and gas in smart cities \cite{houssein2024internet}.
 \cite{shatat2024smart} states that IoT-enabled smart grids can monitor and analyze energy usage patterns, allowing for better load balancing and demand response so that the energy is distributed to areas with the

 Waste bins equipped with IoT sensors send fill-level data to a central system, allowing waste management companies to optimize collection routes and schedules \cite{shatat2024smart}. This not only reduces operational
 costs but also minimizes the environmental impact of waste collection by reducing fuel consumption and emissions due to unnecessary trips \cite{shatat2024smart}.
