Abstract Smart cities utilise a large number of heterogeneous devices with goal to improve all aspects of city operations. This often includes critical functionality, which brings strict requirements on network communication. One of the most important requirements is network latency. This paper analyses latency requirements in areas of smart cities and related domains. Analysed requirements are then practically tested in use case networks based on software-defined networking—a modern paradigm of network programmability, which is becoming used in various areas, including smart cities. The goal of the testing is to verify, if software-defined networking can achieve analysed requirements and can be therefore safely utilised as a driving technology of smart cities. Realistic results are achieved by testing in two different scenarios: In a small scale network composed from real hardware devices, and in a large scale emulated network corresponding to a typical smart city topology. © Springer Nature Switzerland AG 2020.
