Controlling Energy Demand in Mobile Computing Systems

Abstract

Mobile computing and pervasive computing represent major evolutionary steps in distributed systems, a line of research and development that dates back to the mid-1970s. Although many basic principles of distributed system design continue to apply, four key constraints of mobility have forced the development of specialized techniques. These include: unpredictable variation in network quality, lowered trust and robustness of mobile elements, limitations on local resources imposed by weight and size constraints, and concern for battery power consumption. Beyond mobile computing lies pervasive (or ubiquitous) computing, whose essence is the creation of environments saturated with computing and communication, yet gracefully integrated with human users. A rich collection of topics lies at the intersections of mobile and pervasive computing with many other areas of computer science.

Energy efficient computing by using of software optimization aimed on execution time

“…At the moment most of electronic components are built by using complementary metal-oxide semiconductor (CMOS) technology. This technology was discovered by different authors [7,8] and all effects which lead to higher power consumption are known. All sources of CMOS digital circuits power dissipation can be divided onto 4 groups.…”
