Cloudlet-based Augmentation of Mobile Devices

Although Cloud services support wide range of mobile applications, access to Cloud services suffer from several performance issues such as WAN latency, jitter, and packet loss. Frameworks based on the concept known as Edge Computing, Fog Computing or Cloudlet have been proposed to overcome these performance issues. More specifically, Cloud Edge or Cloudlet aims to bring the Cloud or a specific part of the Cloud closer to the mobile device by utilizing proximate computing resources to augment mobile devices. In our proposed framework AD-LET, proximate mobile devices come together to share their resources and create a Cloudlet. AD-LET is self-managing, scalable and can share resources among different types of mobile devices. Experimental results have shown that AD-LET can significantly improves the capability of a mobile device. It augments mobile device thus enabling it to perform resource intensive tasks in the absence of a Cloud or near by infrastructure resources. The layered structure of our framework makes it extensible and allows it to support many types of services and application frameworks.
