Dynamic Resource Management and Cyber Foraging

Abstract

Mobile devices such as PDAs and mobile phones are rapidly advancing to become full-fledged personal computing devices. In particular, besides supporting phone calls, mobile phones nowadays provide storage, computing, communication, and multimedia capabilities thus to be considered the primary personal computing devices of the future [68]. However, although relatively powerful, mobile devices will always be constrained in terms of physical size, thus leading to limitations in their computing and communication capabilities, battery lifetime as well as screen and keyboard size. These constraints inhibit mobile devices from fully supporting increasingly demanding mobile applications. Furthermore, although processing capabilities have followed Moore’s law for the last 30 years, the more critical resource on mobile devices is battery energy density, which has shown the slowest trend in mobile computing [651].
