Internet of Things (IoT) computing offloading is a challenging issue, especially in remote
areas where common edge/cloud infrastructure is unavailable. In this paper, we present a
space-air-ground integrated network (SAGIN) edge/cloud computing architecture for
offloading the computation-intensive applications considering remote energy and
computation constraints, where flying unmanned aerial vehicles (UAVs) provide near-user
edge computing and satellites provide access to the cloud computing. First, for UAV edge …
