TITLE: Scalable Crowd-Sourcing of Video from Mobile Devices

ABSTRACT:
We propose a scalable Internet system for continuous collection of crowd-sourced video from devices such as Google Glass. Our hybrid cloud architecture, GigaSight, is effectively a Content Delivery Network in reverse. Users can perform content-based searched on the total catalog of videos from which privacy sensitive information has been automatically removed. The GigaSight architecture addresses the issue of edge analytics on high datarate sensors.

BIO:
Pieter Simoens is affiliated with Ghent University, Belgium. He obtained his Ph.D. in 2011 on remote display protocols for mobile cloud computing. His main research interests include service-oriented cloudlet infrastructure and networking for mobile users.

TITLE: Just-in-Time Provisioning for Cyber Foraging

ABSTRACT:
Cloud offload is an important technique in mobile computing. VM-based cloudlets have been proposed as offload sites for the resource-intensive and latency-sensitive computations typically associated with mobile multimedia applications. Since cloud offload relies on precisely-configured back-end software, it is difficult to support at global scale across cloudlets in multiple domains. To address this problem, we describe just-in-time (JIT) provisioning of cloudlets under the control of an associated mobile device. Using a suite of five representative mobile applications, we demonstrate a prototype system that is capable of provisioning a cloudlet with a non-trivial VM image in 10 seconds. This speed is achieved through dynamic VM synthesis and a series of optimizations to aggressively reduce transfer costs and startup latency.

BIO:
Kiryong Ha is a PhD student at Carnegie Mellon University. He received BS and MS from KAIST in 2005 and 2007. Prior to join CMU, he was a research staff at ETRI, the Korean government research institute, and he worked on virtualization system to provide seamless working environment for mobile user. His research interested spans to mobile computing, virtualization and cloud computing. He is currently working on Cloudlet project under Professor Mahadev Satyanarayanan.
