Toards Green ICT [Hardcover]

ICT is playing an increasingly important role in both business and private life. It has increased international interconnectedness and sped up the process of globalization, but on the other hand, the total energy consumption by the communication and networking devices and the relevant global CO emission is increasing exponentially. ICT has, in many ways, a vital role to play. It accounts for about two percent of global CO emissions. Telecommunications applications can have a direct, tangible impact on lowering greenhouse gas emissions, power consumption, and achieve efficient recycling of equipment waste.

Towards Green ICTis the outcome of the special session on Green Communications at 'The 12th International Symposium on Wireless Personal Multimedia Communications' (WPMC) held in September 2009 in Sendai, Japan. To the best of the editors' knowledge, this is the first book on the Green Information and Communication Technologies (ICT) and can be considered a milestone and a key tool aimed at driving the industrial, scientific, and academic efforts of the international community to guarantee a greener future to the whole planet.

Section One of this book provides the necessary background and technical content to understand the vision and the role of green communication. It is packed with details on the technologies like Zigbee and RFID in turning the planet greener. Section Two covers a number of paradigm-shifting technical approaches including energy-efficient deployment through optimizations in the planning of ICT networks, energy-efficient wireless transmission techniques, reduced transmission power & reduced radiation, cross-layer optimization methods, and opportunistic spectrum sharing without causing harmful interference pollution. Section Three covers the application of Intelligent WiMAX (I-WiMAX), a green radio technique able to support new maritime communication services and ICT based Business models.
