Smart cities are becoming a reality, due to the enormous research into the technology enabling the development of the Internet of Things (IoT), which has a multitude of applications built around various types of sensors. To manage the increased population of cities, there is a need to have more sustainable, environmental and economical friendly smarter cities and technologies. Recently, a number of smart devices appeared on a large scale, such as the SleepNumber smart bed with its focus on health during sleeping, the Kolibree smart toothbrush, and the Belkin smart saucepan. These are the few with more applications and products to be showcased in the recent future.

In the context of this Special Issue, we define a smart city as a collection of entities (living and non-living) in an urban area that is always connected, fully aware, auto-managed, self-secure, adaptive and well-informed. Furthermore, the growing footprint of ultra-high-speed broadband networks, pervasive wireless networks, cloud computing, crowd sensing, and software-defined infrastructure connect smart/mobile devices to generate relevant city data on a massive scale. These advances will enable transformative applications and services that will enhance the quality of peoples’ lives while addressing important national priorities such as real-time tracking, security, authenticity, and availability of classified information to decision makers. Similarly, to make a smart city, a strong communications infrastructure is required for connecting smart objects, people, and sensors. For instance, audio and video sensors support a variety of safety (monitoring) and non-safety applications. Communication within cities involves multiple aggregation and access networks that can be either public or private. A city may gather data from smart devices and sensors embedded in the roadways, power grids, buildings, and other assets. It shares that data via a smart communications system that is typically a combination of wired and wireless networks. It then uses smart software to create valuable information and digitally enhanced services such as health care assistance, security and safety, real-time traffic monitoring, and managing the environment.

In this Special Issue, we aim to bring together researchers, academics, individuals working on selected areas of smart cities along with new emerging technologies and share their new ideas, latest findings, and results. Both original research and review articles are welcomed.
