Abstract: Mobile devices are increasingly being relied on for tasks that go beyond simple connectivity and demand more complex processing.   In cases where such processing exceeds a device's capability, remote cloud resources can be used to off-load the "heavy lifting" needed by mobile computation tasks. The Cirrus Cloud project focuses on the design and analysis of techniques that enable the provision of cloud computation services to mobile devices. The project is distinguished by 1) its consideration of specific challenges of the wireless and mobile environment and 2) its focus on leveraging the computational capability of a variety of entities present in a mobile device's environment in an opportunistic manner.  In this talk I will first give an overview of the Cirrus Cloud project and its aims. I will then describe some of our work within the project that addresses the following questions: Can one bridge the gap between mobile computation requirements and traditional public cloud computing services? How can one configure clusters of mobile devices into a meaningful edge compute resource? Does it make sense to make edge computing resources mobile and what might be the challenges of such a deployment? 

Bio: Mostafa Ammar is a Regents' Professor with the School of Computer Science at the Georgia Institute of Technology. He has
been with Georgia Tech since 1985. Dr. Ammar received the S.B. and S.M. degrees from the Massachusetts Institute of Technology i
n 1978 and 1980, respectively and the Ph.D. from the University of Waterloo, Ontario, Canada in 1985. Dr. Ammar's research
interests are in network architectures, protocols and services. He has contributions in the areas of multicast communication and
services, multimedia streaming, content distribution networks, network simulation, disruption-tolerant networks, and most recently,
in mobile cloud computing and network virtualization. He has published extensively in these areas. To date, 35 PhD students have
completed their degrees under his supervision; many have gone on to distinguished careers in academia and industry. Dr. Ammar
has served the networking research community in multiple roles. Most notably, he served as the Editor-in-Chief of the IEEE/ACM
Transactions on Networking (ToN) from 1999 to 2003, and he was the co-TPC Chair for the IEEE ICNP 1997, ACM CoNEXT 2006 and
ACM SIGMETRICS 2007 conferences. He currently serves on the steering committee of the IEEE Transactions on Mobile Computing.
His awards include the IBM Faculty Partnership Award (1996), Best Paper Award at the 7th WWW conference (1998), the GT
Outstanding Doctoral Thesis Advisor Award (2006), the Outstanding Service Award from the IEEE Technical Committee on Computer
Communications (2010), the ACM Mobihoc Best Paper Award (2012), and the GT College of Computing Faculty Mentor Award (2015).
Dr. Ammar was elected Fellow of the IEEE in 2002 and Fellow of the ACM in 2003.
