Improving battery life and performance of mobile devices with cyber foraging

The number of mobile phones has grown greatly during the last few decades. Among this trend, also the expectations and requirements we pose on the mobile devices is growing. As the hardware restrictions for efficient computing are slowly removed, the problem of battery life still exists. Current solutions for extending battery life take into consideration very strict energy saving methods as well as building larger batteries. This paper takes a look into saving battery life via remote execution method known as cyber foraging. In cyber foraging the mobile device can use nearby free computing resources to perform more complex tasks instead of executing them locally. A series of tests were carried out in order to evaluate the possibility of saving energy via remote execution. Not only this seems efficient for saving battery life, but also reducing computation times and improving the user experience.
