Conclusion

Objectives

• • To understand the sensing, communication, and control needs of a smart city.
• • To understand the demand posed on radio spectrum by smart devices in a smart city and what technologies are available to meet these needs.
• • To become familiar with the basic concepts of cognitive radio (CR) and how it allows for efficient use of radio spectrum in a smart city.
• • To consider one solution for CR network organization–frequency envelope modulation (FEM) as a possible means for efficiently communicating spectrum state information for wireless networks with potentially hundreds of nodes.

4.1 Introduction

Smart cities of the future, “tomorrowland” if you will, are not static entities, but organic beings with interconnected parts that exchange goods, services, and information. The world's population has become increasingly more urbanized and is expected to continue to do so in the future [1]; therefore finding ways to optimize the efficiency of interactions within a city is of paramount importance. In the past, cities accomplished this through the use of market economies, manually guided and/or powered transportation, ...
