Spontaneous Proximity Clouds: Making Mobile Devices to Collaborate for Resource and Data Sharing

摘要

The base motivation of Mobile Cloud Computing was empowering mobile devicesby application offloading onto powerful cloud resources. However, this goalcan't entirely be reached because of the high offloading cost imposed by thelong physical distance between the mobile device and the cloud. To address thisissue, we propose an application offloading onto a nearby mobile cloud composedof the mobile devices in the vicinity-a Spontaneous Proximity Cloud. Weintroduce our proposed dynamic, ant-inspired, bi-objective offloadingmiddleware-ACOMMA, and explain its extension to perform a close mobileapplication offloading. With the learning-based offloading decision-makingprocess of ACOMMA, combined to the collaborative resource sharing, the mobiledevices can cooperate for decision cache sharing. We evaluate the performanceof ACOMMA in collaborative mode with real benchmarks Face Recognition andMonte-Carlo algorithms-and achieve 50% execution time gain.
