Connecting Cloudlets as Wireless Mesh Network for Result Delivery Through Connection Forecast
Mobile cloud computing offers a solution for offloading high intensity tasks to the cloud and to overcome certain barriers of mobile computing such as computation and data storage capacity. Offloading tasks to the clouds require high bandwidth Internet connectivity which cannot be assured always for the users. Cloudlets bring the clouds closer to the end users to overcome the latency and bandwidth problems. Cloudlets make use of the locally available devices as a computing platform for the mobile devices. However, cloudlets are range restricted, mobile users should be within the range of a cloudlet device to receive the result. When the mobile user moves out of the cloudlet range results are either offloaded to the cloud or discarded. In this work we address the range restriction problem by connecting the cloudlet devices and distributing the results through connection forecast. Connected cloudlets share the responsibility of result distribution providing the users with the opportunity to use the cloudlet service over a larger area. We demonstrate the approach to turn low resource devices into cloudlets. We show how we overcome the range restriction issue and evaluate the work based on network metrics. Places like coffee shops, offices, hospitals can implement the approach of this work to provide services over a wider area and at a low cost.
