Namboodiri, V: Algorithms

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 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.
