Abstract

Mobile devices have recently become so pervasive that they are increasingly replacing personal computers in everyday activities. However, due to their limited resources, mobile devices cannot offer the same performance of personal computers and workstations. One option to overcome such limitations is given by remote desktop access, wherein the mobile device uses thin client software to connect to a remote desktop host. When such host is virtualized, remote desktop access becomes a form of mobile cloud networking. Unfortunately, most of the widely used protocols for remote desktop access on mobile devices have been designed for scenarios involving personal computers. Furthermore, their energy consumption at the mobile device has not been fully characterized. In this thesis, we specifically address energy consumption of mobile cloud networking realized through remote desktop technologies. In order to produce repeatable experiments with comparable results, we design a methodology to automate experiments with a mobile device. Furthermore, we develop an application that allows recording touch events and replaying them for a certain number of times. Moreover, we analyse the performance of widely used remote desktop protocols through extensive experiments involving different classes of mobile devices and realistic usage scenarios. We also relate the energy consumption to the different components involved and to the protocol features. Finally, we provide some considerations on aspects related to usability and user experience.
