Chapter 9 Energy Conservation: Power Life Issues
Mobile computing is evolving rapidly with advances in wireless communications and wireless networking protocols. Despite the fact that devices are getting smaller and more efficient, advances in battery technology have not yet reached the stage where a mobile computer can operate for days without recharging. While research is on-going to build long-lasting batteries, sometimes we wonder if there is an electrochemical limit. If so, then advanced power conservation techniques are necessary. Hence, in this chapter, we will discuss properties of batteries and power management at the device, protocol, and application layers.
Wireless transmission, reception, retransmission, and beaconing ...
