Majority of the devices that are used in ubiquitous computing are expected to be as small as possible, be able to perform as many computations as possible, and transmit the results to another device or computer. Such expectations in performance put a pressure on the power budget of such devices. It is a well-known fact that the advances in battery technology are much slower and cannot keep up with the performance demands of tiny gadgets unless new methods of designing and managing hardware and software are developed and used. This chapter will introduce the motivation for low power design considerations by discussing the power limitations of ubiquitous computing devices. Then the chapter will discuss the research directions that are being pursued in literature for reducing power consumption and increasing efficiency of ubiquitous computing systems.
