The widespread idea of cloud computing affects developing approaches of mobile applications. With ubiquitous computing capabilities and mobile devices, one question arises for mobile application developers: How could battery drainage be reduced? To combine the cloud computing services and mobile applications, an offloading of processes may produce a benefit to save battery life. For example, background processes are mainly uninteresting for mobile users and can be offloaded to the cloud, as well as image processing or searching. Only a feedback mechanism is necessary to obtain results of a process in the cloud. With already existing technologies, an approach based on actors seems to be able to handle code offloading. By avoiding the pitfalls of this concept, system designers, who identify battery and processing power consuming applications, can offload critical code to an actor in real-time. The signalling concept is analysed with existing web-service technologies and described by a messaging paradigm, which fulfills the actor’s requirements. A trial architectural design demonstrates the functionality of real-time code offloading on mobile devices.
