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...
