Abstract. Smartphones have become a daily companion in recent years due to their small form factor. However, such mobile systems are resource-constrained in view of computational power, storage and battery life. Offloading resource-intensive tasks (aka mobile cloud computing) to dis-tant (e.g., cloud computing) or closely located data centers (e.g., cloudlet) overcomes these issues. However, in emergency case (e.g., blackout) con-ventional offloading concepts are no longer available while battery life of mobile devices becomes crucial. In this paper, we extend our previous concept of upgrading wireless home routers as cloudlets by an emergency power extension (i.e., off-the-shelf battery pack) to provide computing infrastructure during an emergency case. Our conducted runtime mea-surements show the feasibility of this concept. As preliminary result, we are able to run a large-scale deployable emergency cloudlet over 5 hours autarchically under full load.
