Abstract
The revolution of the Internet and the Internet of Things (IoT) has led to the development of numerous devices, such as radio-frequency identification tags, sensors, and other intelligent devices. Devices with significant computational capabilities and those that are transformed into intelligent objects are used to monitor and gather information about the environment of a city, thereby leading to smart cities. The most important problem that is currently experienced by smart cities is waste management problem. The following factors directly affect this problem: an increase in urban areas and rapid population growth. Intelligent services can function as the frontline in obtaining information regarding every aspect of human activities. A typical example of a service provided by smart cities is waste management supported by IoT. Waste management involves different responsibilities, such as the collection, disposal, and utilization of waste in relevant facilities. A review of common waste management models is presented in this paper. Then, an enhanced waste management design is proposed. This design considers and deals with population and urban growth by using different truck sizes according to waste type and IoT devices that ease communication among system entities, such as smart bins, waste source areas, waste collection trucks, and waste management centers.
