Algorithms & Protocols Towards Energy-Efficiency in Wireless Networks

A plethora of wireless technologies promise§ubiquitous communication in the future. A major§impediment to this vision is limited energy supply§from batteries in these devices. Energy supply has§far reaching implications on user experience as well§as practicality of many envisaged applications. The§energy consumed for radio communication in these§devices is a major factor in the operating lifetimes§of these devices. This calls for design of network§protocols and algorithms that reduce energy§consumption due to the wireless interface. In this§book we look at three emerging application scenarios§of wireless networks, namely: (i) VoIP calls over§Wireless LANs (ii) Tag Anti-Collision Protocols for§Radio Frequency Identification (RFID) systems, and§(iii) Topology Control Algorithms for Wireless Mesh§Networks. We present techniques to make radio§communication energy-efficient in these scenarios§along with evaluations proving their effectiveness.§Moreover, guidelines are presented on how such§techniques can be extended to achieve energy§consumption reductions for other application§scenarios. This book is a§timely read in a world that is increasingly energy-§aware.
