Resourced-constrained mobile devices could enhance the performance of their applications and extend their battery life by resource augmentation techniques where more powerful computing sources support the mobile devices. This presentation explores the challenges in this area in the context of both Cyber Foraging Systems where supporting computing sources exist within the local network and Mobile Cloud environment where these sources exist in the cloud. We will look at the various issues involved when mobile devices have to make a decision to augment their resources by offloading their tasks. More precisely, we will first show why a broker node is important in situations where a large number of mobile devices are present in a local network. Then, since mobile devices are energy constrained, we will look at the tasks offloading problem in the context of energy minimization. Finally, some trade-offs related to task offloading will be discussed.
