Energy-efficient Execution of Mobile Services using Flexible Cloud Platforms

Two recent trends are major motivators for service compo- nent migration: the upcoming use of cloud-based services and the increasing number of mobile users accessing the Internet-based services via wireless networks. While cloud- based services target the vision of Software as a Service, where services are ubiquitously available, mobile use of such services impairs the battery life of the device caused by ad- ditional network communication between the cloud and the mobile device. This paper investigates service component migration between the mobile client - as part of the cloud - and the infrastructure-based cloud as a means to save energy of the mobile device. Hereby, migration decisions are control- led by policies. A Markov modelling approach to calculate optimised policies with respect to energy consumption at the client is introduced and applied to an example scenario
