Smart City is a city that uses Information and Communication Technologies (ICT) to improve the quality of service, share information with people, and improve the quality of public services but the well-being of citizens.

The first question is what ‘smart city’ entails.

The response is that there is no widely agreed concept of a smart city. It means different things for different people. The conceptual model of Smart City, therefore, varies from place to place and country to country, based on the level of development, ability to change and reform, resources as well as aspirations of people living in cities.

How Smart city work?

Smart cities use a mix of Internet of Things ( IoT) tools, technological applications, user interfaces (UIs), and communications infrastructure. The IoT is a network of smart IoT devices — such as cars, sensors, or home appliances — that can communicate and exchange data with the server.

Data obtained and distributed by IoT sensors and computers shall be processed in the cloud or on servers. Connecting these tools and using data analytics (DA) enables the integration of physical and digital urban elements, thereby enhancing the productivity of both the public and private sectors, creating economic gains and improving the lives of people.

IoT systems also have a processing power called Edge computing and the system called the Edge system.

Edge computing means that only the most significant and appropriate information is transmitted through the communication network.

Technologies Used in Smart City

  • API (application programming interfaces)
  • Cloud Computing
    • Servers
    • UI (User Interface)
  • Embedded System
  • Machine Learning (ML)
  • Artificial Intelligence (AI)
  • IoT Protocols
    • MQTT
    • Wifi
    • IPv 4/IPv 6
  • Networking Protocols
    • mesh network

Smart City Features

  • An adequate supply of water,
  • Ensuring electricity supply,
  • Sanitation, including the management of solid waste,
  • Efficient urban mobility and public transport;
  • affordable housing, particularly for the poor,
  • Robust IT connectivity and digitalization,
  • Good governance, in particular e-government and citizen participation,
  • Sustainable environment;
  • Safety and protection of people, particularly women, children and the elderly, and
  • Health and schooling, too.

Example of Smart city

1. Smart Lighting Solution.

The lighting control system is an advanced network-based lighting control solution that integrates communication between different device inputs and outputs related to lighting control with the use of one or more central computers.

Lighting control systems are commonly used for both indoor and outdoor lighting in commercial, industrial, and residential areas. Lighting control systems are used to provide the right amount of light where and when it is needed.

2. Smart Camera Sensors Network

Smart camera networks are real-time distributed embedded systems that use multiple cameras to perform image processing. This new approach has emerged as a result of the confluence of simultaneous advances in four key disciplines: computer vision, image sensors, embedded computing, and sensor networks.

3. Smart Metering System

A Smart Metering system is a network of smart meters. Which can store all the power parameters like power consumption (KwH), power factor(pf), wattages(W), And these meters are powered with wifi and GSM that can use to send the metering data to the server, and this data is used for real-time monitoring and bill generation.

Concussion

The concept of a Smart city is basically used to reduce physical involvement and improve the quality of service and real-time data analysis and its advantages of a smart city.
