A smart city environment utilizes different types of Internet of Things (IoT) devices, i.e., sensors and actuators, to collect and analyze millions of data to manage assets, resources, and services efficiently to improve the quality of life. However, the data collection process is one of the most challenging tasks for smart cities. To meet the requirements of smart city applications, a robust and efficient data collection process is needed to collect data from IoT devices then deliver it to data centers. This paper proposes an end-to-end data collection architecture from IoT devices for different smart city applications, such as smart buildings, transportation, smart grids, healthcare, and others, through advanced communication technologies and protocols and database management approaches. The proposed architecture includes five main components, (1) IoT Networks, (2) Server-side MQTT Interfacing, (3) Server-side Streaming, (4) NoSQL Database, and (5) Web Server. Finally, this paper provides a case study to demonstrate the effectiveness of the proposed architecture and discuss each design component in detail.
