The worldwide smart cities market refers to the industry that is focused on developing and implementing smart city technology. Products and services in this market make use of digital technologies such as cloud computing, artificial intelligence (AI), big data, and the internet of things (IoT) to enhance urban infrastructure, optimize municipal operations, and promote sustainability. Due to population increase and urbanization, sustainable constructions are now necessary for market expansion. Several regional governments are trying to address these concerns by developing smart city initiatives in a variety of categories, such as management, safety, utilities, and mobility. Furthermore, local governments have been at the forefront of efforts to support organizational and institutional reforms, enable steady investments, and build a consortium to bring different businesses together. Additionally, the global market for smart cities is significantly influenced by government funding programs and initiatives. For instance, India\'s Smart Cities Mission, which began in 2015 and has spent USD 17.2 billion, has finished 91% of its projects. This approach combines pan-city initiatives with area-based development to enhance sustainability, governance, and urban infrastructure. However, one major obstacle to the smart town\'s economy is the large upfront costs associated with putting smart infrastructure and technologies in place. Integration of IoT devices, sensors, and communication networks requires significant financial resources, which may be unaffordable for municipalities with limited funds. It might also be challenging to oversee multiple parties and guarantee compatibility across various platforms.
