1.1 Introduction

Wireless communication has been experiencing tremendous advancements. These developments have triggered new wireless networking paradigms and communication services. For instance, 5G is being studied by the research community to provide mobile broadband communications in wireless networks. Recently, the concept of IoT (Atzori et al., 2010), which is one of the key elements of 5G wireless networks, has been proposed to connect every device to the Internet, such as wireless sensor nodes, RFID tags, household appliances, etc.

As these technologies grow, they have been applied to various real‐world problems. One of the most important application areas is the management of cities in a more efficient and smarter way. The smart city is a vision that extracts information from systems in the city to take measures for its management. This vision can be realized if information and communication technologies are employed in these systems to observe and manage them. Wireless sensors can be utilized as key elements for observing systems such as hospitals, highways, transportation networks, and power grids ...
