Introduction Our lives are being transformed by the interplay between mobile networks, wireless communications, and artificial intelligence. This transformation is an outcome of the emerging Internet of Things (IoT) concept, and the advancements in computer architectures that translate into high computing power, high-performance processing, and huge memory capacities. In addition to the IoT, as a very close concept, cyber–physical systems target seamless integration of physical systems with computing and communication resources. Furthermore, in urban areas, the integration of the “software-defined sensor networks” and “sensing as a service” concepts with legacy Wireless Sensor Network (WSN)-based systems is leading to the transformation of conventional city services towards smart cities. Smart energy, smart driving, smart homes, smart living, smart governance, and smart health are just a few services that can be offered by smart cities. Furthermore, while these concepts are major application areas, smart citizens close the loop by participating in sensing, actuating, and decision-making processes. In smart cities, legacy WSN-based services are extended by having citizens that act as sensors. Opportunistic or participatory sensing models enable groups of individuals to collaboratively work toward the same goal with strong interaction links, even though this does not always require strong social links between them. Thus, dedicated and nondedicated wireless sensors form communities, and collaborating communities form social networks where interaction can occur in the form of software-defined sensing. This transformation in WSNs introduces unique solutions for the communication plane of smart cities. In addition to communication-plane challenges, smart environments require IoT and WSN sensors to report massive amounts of unstructured data in a heterogeneous format, which, in turn, leads to the big sensed data phenomenon. Additionally, addressing the high volume by effective machine-learning or data-mining techniques, novel data-acquisition and -processing methodologies for big sensed data are emergent in order to address the high-velocity, -variety, and -veracity aspects. Moreover, in order to effectively offer smart-city services, it is viable to envision a massive amount of connected wireless/wired sensors/IoT devices. Thus, scalability remains an open issue when integrating the components of a smart city that are mentioned above. While ensuring the scalability and connectivity of this infrastructure remains an open issue, the battery limitation of wireless sensors
