The cloudlet with a silver lining

Cyber-foraging makes resource-constrained mobile devices more powerful by using the resources elsewhere in the network. Just-in-time cyber foraging with dynamic VM synthesis has been proposed to increase the performance of mobile devices, which connect a nearby fixed device - called a cloudlet - and borrow its capabilities. The cloudlet runs an instance of the VM of mobile device and the application (app) on it. However, off-loading itself may consume time and memory, leading to poor performance of the app. When there are many cloudlets within range of the mobile device, choosing just any cloudlet to connect to may lead to avoidable and noticeable delays and poor performance of the application. In this paper, we propose a scheme where the best possible cloudlet can be identified by the mobile device to connect to. The choice of the cloudlet should be based on several factors like its processing power, available memory and bandwidth and the nature of the app itself. By choosing a cloudlet more suited for the application as the site of cyber-foraging, we aim to improve the performance of the mobile application.
