Smartphone Based Computing Cloud and Energy Efficiency

Modern research and engineering problems often require a lot of computing power to find a solution. Mobile devices are usually considered as having not enough computing power to conduct complex evaluation, and their power sources are limited to sustain intensive computation for long. However, mobile devices are supposed to have higher energy efficiency, hence this is a matter of finding a good way of utilizing those advantages. Another good reason to utilize mobile devices for computation is they are already in service. According to public statistics it's about 15 billion mobile devices currently in service, and the number may exceed 18 billion by the mid 2020s [2]. Due to rising demand on cloud infrastructure it may be wiser to utilize existing computing than building new ones.
