provides a practical
platform for performing face recognition on a mobile device.
However, using a mobile-cloud architecture to perform real-time
face recognition presents several challenges including resource
limitations and long network delays. In this paper, we determine
three approaches for accelerating the execution of the face
recognition application by utilizing an intermediate device called
a cloudlet. We study in detail one of these approaches, using the
cloudlet to perform pre-processing, and quantify the maximum
attainable acceleration. Our experimental results show up to a
128× improvement in response time when appropriate cloudlet
hardware is used
