Improving Efficiency and Extending Battery Life by Offloading Mobile Computation to Cloud

Mobile cloud computing is fast taking over the world by storm as the spread of smart phones soar and have become the primary replacement for desktop for many users. Various studies have identified longer battery lifetime as the most desired feature of such systems. Computing resources such as processing, memory, and storage are not physically pres¬ent at the user’s location. But in case of smart phones processing virtually reduces the battery life of the phone and also heats up the device. The cloud heralds a new era of computing where numerous application services are provided which enhances the capability of mobile devices but the major problem faced is the rapid energy depletion in the batteries. The focus is to provide a solution for extending the mobile battery lifetimes. Cloud provides application services through internet. Thus mobile cloud can enhance and extend the capability of mobile systems processing power. A cloud service provider owns and manages these resources, and users access them via the Internet. The primary constraints for mobile computing are limited energy and wireless bandwidth wherein vendors provide computing cycles to do such tasks by the devices applications installed on the cloud platform and thereby reduce computation on mobile devices and thus save battery energy. Thus, cloud computing can save energy for mobile users through computation offloading. By using mobile cloud computing platforms energy savings in mobile devices will be a reality. The study focuses on the process of mobile computation offloading to the cloud thereby extending battery life, reducing memory and cpu usage thus saving valuable resources.
