Green Communication for Cognitive Cities

Abstract

To meet the explosive data rate requirements of future cognitive cities, mobile and wireless technologies are evolving at a very fast pace. With the faster adoption of bandwidth-hungry applications in our daily lives, the energy consumption in wireless networks has increased. Higher energy consumption has imposed some serious health concerns such as exposure to harmful radiation and increase in carbon dioxide emissions into the environment. To overcome the ecological and health issues and to meet the end user's high data rate requirements for the successful deployment of the cognitive cities, the most important technology is green communication. Taking into consideration the importance of green communication technologies, this chapter presents an intense survey on energy-efficient technologies developed for green communication. Some key research challenges pertaining to the use and deployment of these technologies for green communication are discussed. In the end of this chapter, the worldwide standardization efforts for cognitive cities are also highlighted.
