Guest Editorial: Introduction to the Special Section on Data-Driven IoT for Smart Cities

The papers in this special section focus on data-driven Internet of Things (IoT) for smart cities. Developing smart cities to better support the growing urban population is a global and complex challenge and involves interdisciplinary fields. Instead of the traditional Internet of Contents in human-to-human and human-to-machine communications, the Internet of Things with communications among massive numbers of sensors will dominate the network traffic. Every day, these smart things generate a massive amount of data in the magnitude of ZettaBytes. Due to inherent characteristics of geo-distribution in big data generated by networked sensors deployed for IoT applications, the “smartness” of infrastructure in future cities requires intelligent data sensing and mining for monitoring and actuation to ensure infrastructure reliability and public safety.
