### Strategic Policies for Boosting Economic Recovery of Smart Cities through the IoT  
The IoT technology inherent in smart cities, promises effective options that will allow cities to be more safe, inclusive, and resilient [61]. In this regard, the IoT helps cities to improve good governance and privacy which are important for the socio-economic dimensions of urban areas [62]. In addition, the advance of 5G technologies [63] and artificial neural networks (ANNs) will prompt further innovations in smart city technologies of the IoT [64]. In fact, cloud-based IoT applications that contain information gathered from citizens could help smart cities to monitor and manage crime detection, proficiency, water supply systems, healthcare facilities, electric utilities, digital libraries, transportation networks, resource management, waste management, and security mechanisms [65]. Therefore, smart technologies such as the IoT are significant when developing SCs, while maintaining emphasis on the implemented strategies and policies [66]. It is clear that the implementation of targets related to SCs requires strong and calculated strategies and policies [67]. In fact, achieving \"smartness\" is not a one-time action; it is a continuous process. Therefore, policymakers should aim to devise a plan [68] that considers the individual goals of each sector whilst also evaluating the dynamic and indirect impacts on other areas within an SC. Undoubtedly, to advance SCs and continue their expansion, officials and policymakers must vigorously strive to create a unique quality of life, work, and environment for the citizens of their cities [69]. On the other hand, since the concept of SCs falls in line with the smart grid, economic issues related to the programs that are used for demand-response management (DRM) and real-time pricing should be taken into consideration [70]. In addition, it can be added that as SCs aim to improve the quality of life of urban citizens, the success of SCs depends on participation by private companies [71]. Therefore, through the use of new communication channels between the government and its citizens, policymakers should focus on the essential needs of stakeholders, such as affordable energy, urban security, and energy security [69], because, public participation will help improve quality of life and establish trust between local governments and people [72]. This means that the investment in developing SCs has advantages for both people and the community, including a reduction in the cost of living, improvement of living standards and environmental sustainability, improvement of operational efficiency, improvement of eco-friendly infrastructure, and development of smart technology through the IoT [73]. Moreover, private investment (companies) can help governments easily overcome old issues pertaining to big cities or developing cities that have not been well planned [74]. In general, investment on IoT technologies, is opening new possibilities for cities and helping them to be smart cities [75]. According to these cases, effective strategies and policies can accelerate the conversion of a standard city into an SC and, thus, should aim to attract investment, improve IT infrastructure, integrate connected local energy storage systems in order to support better renewable energy sources on the power grids, and adapt an IoT implementation strategy based on the city's size to reduce costs, support the utilization of smart LED streetlights in major metropolises, increase the collaboration between local governments and stakeholders, increase the utilization of new technologies such as sensors, change the mentality of the citizens, and redefine the governance model with proper politics.
