An Analysis of the Impact of the Quality of Mobile Networks on the Use of Cloudlets

An increasingly concern in the use of mobile devices is the battery life due to the increase of its embedded sensors and its features. The Mobile Cloud Computing (MCC) paradigm studies how to extend computational resources and the energy of mobile devices through the use of offloading techniques. In this context, cloudlets and the public clouds emerge as alternatives to the execution of cpu-intensive tasks of mobile devices. This paper presents an evaluation of the mobile Internet quality in three cities of the Brazilian northeast and a comparative study between the use of cloudlets and public cloud to perform offloading. Furthermore, the paper discusses the factors that impact the decision making of when and where to offloading.
