Dear colleagues, Below please find the final program of the 7th ACM International Workshop on Mobility in the Evolving Internet Architecture (MobiArch 2012), in conjunction with ACM MobiCom 2012. Your participation is highly appreciated. See you in Istanbul!
Regards, Xiaoming *ACM MobiArch 2012 Technical Program* *August 22, 2012, Istanbul, Turkey* *In Conjunction with ACM MobiCom 2012* ** *9:00 Welcome and workshop introduction* *9:30-10:30 Keynote speech by Lili Qiu (U. Texas, Austin): Cellular Offloading via Auctions * Abstract: The explosive growth of cellular traffic and its highly dynamic nature often make it increasingly expensive for a cellular service provider to provision enough cellular resources to support the peak traffic demands. To defray the escalating costs, the current best practice is to have the cellular service providers deploy alternative wireless technologies, such as Wi-Fi and femtocells, on their own to complement the cellular network. However, this solution is expensive and causes increased interference. In this talk, we present iDEAL, a novel auction-based incentive framework that allows a cellular service provider to leverage resources from third-party resource owners on demand by buying capacity whenever needed through reverse auctions.iDEAL has several distinctive features: (i) iDEAL explicitly accounts for the diverse spatial coverage of different resources and can effectively foster competition among third-party resource owners in different regions, resulting in significant savings for the cellular service provider. (ii) iDEAL provides revenue incentives for third-party resource owners to participate in the reverse auction and be truthful in the bidding process.(iii) iDEAL is provably efficient. (iv) iDEAL effectively guards against collusion. (v) iDEAL effectively copes with the dynamic nature of traffic demands.In addition, iDEAL has useful extensions that address various important practical issues. Extensive evaluation based on real traces from a large US cellular service provider clearly demonstrates the effectiveness of our approach. We further demonstrate the feasibility of iDEAL using a prototype implementation. Short biography: *Dr. Lili Qiu* is an Associate Professor at the University of Texas at Austin. She received MS and PhD degrees in computer science from Cornell University in 1999 and 2001, respectively. Before joining UT in 2005, she spent four years as a researcher at Microsoft Research, Redmond working on Internet and wireless networking research. She received NSF career award in 2006. She has published 70+ papers in leading networking conferences and journals and been issued 16 US patents. She has chaired several networking conferences (e.g., ACM MobiCom, IEEE ICNP, IEEE SECON, WICON), and served as editors for several networking journals (e.g., IEEE Transactions on Mobile Computing, Computer Networks Journal, and Mobile Computing and Communications Review) and program committees of manyconferences. She also serves as Treasurer for ACM SIGMOBILE. She is an IEEE senior member. 11:00-11:30 Morning break *11:30-13:00 Technical session "Mobile DataOffloading", chair: Mario Hoffmann* ·Can Offloading Save Energy For Popular Apps?

We will specifically focus on the opportunities and challenges at the intersection of multi-modal sensing, cloud computing, and data analytics, and describe how carefully fusing them can lead to powerful apps. We will close not only with challenges we are struggling with, but will also discuss new kinds of problems that will gain relevance in the days to come. Short biography:*Dr. Romit Roy Choudhury* is an Associate Professor of ECE and CS at Duke University. He joined Duke in Fall 2006, after completing his PhD from UIUC. His research interests are in wireless protocol design mainly at the PHY/MAC layer, and in mobile computing at the application layer. Along with his students, he received a few research awards, including the NSF CAREER Award, the best paper at Personal Wireless Communications conference, Hoffmann Krippner Award for Engineering Innovations, MobiCom Student Research Contest, etc. See page of his Systems Networking Research Group (SyNRG) at http://synrg.ee.duke.edu *15:50-16:00 -- Technical session "Resource Management", chair: Maria Papadopouli* ·Towards Utility-based Resource Management in Heterogeneous Wireless Networks Ilias Tsompanidis, Ahmed Zahran and Cormac Sreenan ·Context-based Distribution of Points of Interest Mario Hoffmann, Alam Mohammad and Suleman Khan 16:00-16:30 Afternoon break 16:30-17:15 Technical session "Cooperative networks", chair: Xinbing Wang ·Supporting wireless access markets with a user-centric QoE-based geo-database George Fortetsanakis, Michalis Katsarakis, Maria Plakia, Nikos Syntychakis and Maria Papadopouli ·Cooperative Networks: The Mobile Tethering Game Mihai Marius Constantinescu, Ertan Onur, Harry Bouwman, Miodrag Djurica, Mark De Reuver and Yunus Durmus 17:15 Wrap-up _______________________________________________ IEEE Communications Society Tech.
