SIGMOBILE FY'11 Annual Report

July 2010 - June 2011
Submitted by: Roy Want, SIGMOBILE Chair


Building on the expanding field of mobile computing, SIGMOBILE is the ACM Special Interest Group on Mobility of Systems, Users, Data, and Computing. Its scope includes all aspects of mobile computing and communications, such as mobile systems and applications, wireless networking protocols and algorithms, and mobile information access and management. SIGMOBILE is a strong, vibrant SIG, with significant membership, healthy finances, well-respected, successful conferences, workshops, and publications, and valuable services for its members and the community.

The current elected officers in SIGMOBILE's Executive Committee are:

  • Chair: Dr. Roy Want (Google Inc, USA);
  • Vice Chair: Prof. Robert Steele (University of Sydney, Australia);
  • Secretary: Prof. Ramesh Govindan (University of Southern California, USA); and
  • Treasurer: Prof. Lili Qiu (University of Texas at Austin, USA).
This is the second year the Executive Committee has served since the 2009 elections, and includes the Past Chair, Prof. David B. Johnson (Rice University, USA).

Committee Appointed Positions

SIGMOBILE's leadership has four committee appointed positions:
  • Editor-in-Chief (EIC) for SIGMOBILE's journal/newsletter for our members (Mobile Computing and Communications Review or MC2R), Prof. Suman Banerjee (Univ. of Wisconsin, Madison, USA)
  • Information Director Prof. Robert Steele (University of Sydney, Australia),
  • Workshop Coordinator Prof. Ahmed Helmy (University of Florida, Gainesville, USA),
  • Digital Library Coordinator: Dr. Guanling Chen (University of Massachusetts Lowell, USA).
In the Fall of 2011 we will be looking for a new Workshop Coordinator as Ahmed Helmy has stepped down after many years of service. We thank him for all his contributions to make SIGMOBILE Workshops successful.

Sponsorship for the Mobile Computing Research Community

In 2010-11, SIGMOBILE has provided sponsorship in the form of financial support for three programs in the mobile computing research community.
  • The Community Resource for Archiving Wireless Data At Dartmouth (CRAWDAD) continues to be a thriving resource for the SIGMOBILE community. As of July 2011 it contains 70 datasets, each containing one or more traces about wireless networks or mobile users, and 23 tools, many of which are designed to help researchers work with such datasets. There are currently 4 datasets in pipeline for publication. There are 3,151 users from 77 countries around the world. CRAWDAD continues to be increasingly popular, with more than 800 new users registering within the past year. Although the primary archive is at Dartmouth, the CRAWDAD site and data are mirrored on servers located in UK and Australia, to guarantee uninterrupted service and fast downloads to users all around the world.

    CRAWDAD data has supported at least 318 papers in the field, and continues to be the go-to place for authors wishing to share data they've collected, or to obtain data they can use for testing their system prototypes and algorithms. SIGMOBILE support makes it possible for the CRAWDAD project to retain a technical staff person (part time) to add new data sets, maintain the site, and develop new features.

  • Networking Networking Women (N2 Women) is a discipline-specific community for researchers in the communications and networking research fields. The main goal of N2 Women is to foster connections among the under-represented women in computer networking and related research fields. N2 Women allows women to connect with other women who share the same research interests, who attend the same conferences, who face the same career hurdles, and who experience the same obstacles. To assist in its networking goals, N2 Women has an email list for the group:, and there are currently over 480 members.

    N2 Women is an ACM SIGMOBILE program that has been financially supported by SIGMOBILE, Microsoft Research and HP Labs. In the past year, funds from SIGMOBILE were used for the N2 Women Student Fellowship program. A student applies for a Fellowship and, if selected, N2 Women partially covers the student's travel cost (up to $500) to a conference where an N2 Women event will be held. In exchange, the student must help organize the N2 Women meeting. The benefit of doing the organization, in addition to the travel funds, is for the student to connect with the organizers of the conference who are, typically, leaders in the research field. The organization also arranges for a senior member of N2 Women to assist/mentor the student in this task.

    Since June 2010, there have been 11 N2 Women Student Fellows who organized N2 Women events at the following conferences:

    • Farhana Ashraf, University of Illinois at Urbana-Champaign (SECON 2011)
    • Ouldooz Baghban Karimi, Simon Fraser University (SIGCOMM 2011)
    • Yue Liu, University of Michigan) (MobiSys 2011)
    • Yan Qiao, University of Florida (INFOCOM 2011)
    • Yu-Han Chen, National Taiwan University (SenSys 2010)
    • Minlan Yu, Princeton University (SIGCOMM 2010)
    • Afra Mashhadi, University College London (MobiCom/MobiHoc 2010)
    • Lara Deek, UC Santa Barbara (MobiCom/MobiHoc 2010)
    • Michela Papandrea, University of Applied Sciences of Southern Switzerland (SUPSI), (WoWMoM 2010)
    • Pegah Sattari, UC Irvine (MobiSys 2010)
    • Devu Shila, Illinois Institute of technology, Chicago (ICDCS 2010)
    Also thanks to support from SIGMOBILE, N2 Women held the 1st Networking Networking Women Workshop on September 20, 2010 in conjunction with MobiCom/Hoc in Chicago, Illinois. The breakdown of the 65 female attendees is as follows: 33 students (51%), 17 senior researchers (26%), and 15 junior researchers (23%). Overall, there were 47 institutions represented by the attendees. Participants came from all over the US and from as far away as Europe and India, with the following countries represented: Canada, France, India, Spain, Sweden, and Switzerland. We had several participants who attended the conference because they were coming to the N2 Women workshop and several others who attended the N2 Women workshop only (i.e., they did not attend the co-located MobiCom/Hoc conferences). In fact, a few participants traveled from Europe just to attend the N2 Women workshop!

    In all N2 Women announcements, SIGMOBILE (and other sponsors of N2 Women) are thanked. Further details of N2 Women are available at:

  • ACM-W: In 2011 SIGMOBILE has become a sponsor for ACM-W (ACM's Women in Computing organization). "ACM-W's mission is to celebrate, inform and support women in computing, and work with the ACM-W community of computer scientists, educators, employers and policy makers to improve working and learning environments for women." This is an organization that the Executive Committee whole-heartedly supports. This means that women in CS education can request sponsorship for SIGMOBILE conferences, and we will provide sponsorship for travel and registration.

MobiSys 2011, the 9th International Conference on Mobile Systems, Applications, and Services, was held June 28th-July 1st, 2011, in Washington, DC, USA and in-cooperation with SIGOPS. Ashok Agrawala (University of Maryland, USA) served as the General Chair, and Mark D. Corner (UMass Amherst, USA) and David Wetherall (University of Washington & Intel Labs, USA) served as the Program Co-Chairs.

The MobiSys 2011 technical program began with a keynote talk by Dr. Edward W. Felten (Federal Trade Commission) on "Making Progress on Mobile Privacy". Dr. Felten is the first Chief Technologist at the U.S. Federal Trade Commission. He is on leave from Princeton University, where he is a Professor of Computer Science and Public Policy. The final day featured a second keynote by Dr. Douglas C. Sicker (Chief Technologist with the FCC) on "Technology Policy Issues at Federal Communications Commission" Dr. Sicker is the Chief Technology Officer of the Federal Communications Commission (FCC), and also the DBC Endowed Professor in the Department of Computer Science at the University of Colorado at Boulder with a joint appointment in the Interdisciplinary Telecommunications Program.

On June 30th (day 2), the SIGMOBILE 2010 Outstanding Contributions Award (OCA), the most prestigious SIGMOBILE technical award, was presented to Prof Mahadev Satyanarayanan (Satya): "For pioneering a wide spectrum of technologies in support of disconnected and weakly connected mobile clients". Satya's research has always been focused on mobile systems, and hence the choice to present the award at MobiSys, rather than MobiCom. The award was followed by a plenary talk entitled, "Mobile Computing: the Next Decade and Beyond". Satya is an experimental computer scientist who has pioneered research in mobile and pervasive computing. One example of his work is the Coda File System, which supports distributed file access in low-bandwidth and intermittent wireless networks through disconnected and bandwidth-adaptive operation. The Coda concepts of hoarding, reintegration and application-specific conflict resolution are seen in the hotsync capability of mobile devices today. Key ideas from Coda were also incorporated by Microsoft into the IntelliMirror component of Windows 2000 and the Cached Exchange Mode of Outlook 2003. Other examples of Satya´s work include Odyssey (which explored operating system support for application-aware adaptation to overcome resource limitations in mobile computing) and the Internet Suspend/Resume system (a hands-free approach to mobile computing that leverages virtual machine technology). Satya is a co-inventor of many technologies central to mobile and pervasive computing, such as cyber foraging, data staging, lookaside caching, and translucent caching. He is a Fellow of the ACM and the IEEE. He was the founding Editor-in-Chief of IEEE Pervasive Computing and the founding program chair of the HotMobile workshop series.

The last day of the conference (Friday, 1st July), also began with a Keynote from Dr. Douglas C. Sicker (Chief Technologist with the FCC) and a talk titled, "Technology Policy Issues at the Federal Communications Commission". Dr. Sicker has held various positions in academia, industry and government. Presently, Doug is the Chief Technology Officer of the Federal Communications Commission (FCC). Doug is also the DBC Endowed Professor in the Department of Computer Science at the University of Colorado at Boulder with a joint appointment in the Interdisciplinary Telecommunications Program. Doug is a senior member of the IEEE, as well as a member of the ACM and the Internet Society. He has served as an advisory to the Department of Justice National Institute of Justice. After leaving the FCC, he was also the Chair of the Network Reliability and Interoperability Council steering committee and served on the Technical Advisory Council of the FCC. His research and teaching interests include network security, wireless systems and telecommunications policy.

In addition to the conferences and co-located workshops above, SIGMOBILE also sponsors the HotMobile workshop (previously known as WMCSA) as a stand-alone event, not co-located with a conference. The HotMobile workshop series focuses on mobile applications, systems, and environments, as well as their underlying state-of-the-art technologies, in a small workshop format that makes it ideal for presenting and discussing new directions or controversial approaches. The Executive Committee encourages the MobiCom Program Committee meeting be collocated with HotMobile to ensure a representative selection of senior researchers attend the event. This workshop was previously sponsored each year by the IEEE Computer Society, but has been sponsored instead by SIGMOBILE since HotMobile 2008.

HotMobile 2011, the 12th Workshop on Mobile Computing Systems and Applications, was held March 1-2nd, 2011, Phoenix Arizona, USA. Anthony Lamara (Intel Labs, Seattle USA) served as the General Chair, and Landon Cox (Duke University, USA) served as the Program Chair. The HotMobile 2011 technical program featured a keynote by Betsy Masiello (Policy Manager, Google Inc) entitled, "Communication, Information and Organization: The evolving role of mobile technology". Betsy is currently with Google Inc, and has an MSc in Financial Economics from the Said Business School, Oxford University; and a BA in Computer Science and Economics from Wellesley College.

HotMobile 2011 also included a Doctoral Consortium, providing feedback on students' current research and guidance on future research directions, offering each student comments and fresh perspectives on their work from faculty and students outside their own institution, and promoting the development of a supportive community of scholars and a spirit of collaborative research. The MobiSys 2011 program committee meeting was held the day following Hotmobile to encourage participating senior researchers to attend HotMobile, widen the discussions, and support the Doctoral Consortium.

HotMobile 2012 will be held February 2012, in San Diego, California, USA. The General Chair is Gaetano Borriello (University of Washington), and the Program Chair is Rajesh Krishna Balan (Singapore Management University, SG).


SIGMOBILE also sponsored the following high-value events over the last year. These are annual decisions and sponsorship one year does not guarantee support in a following year. If the standard remains high, SIGMOBILE is likely to continue with its support.

  • DIALM-POMC 2010: The Sixth International Workshop on Foundations of Mobile Computing, Sept 16th, 2010, Cambridge, Massachusetts, USA
  • WUWNet 2010: The Fifth ACM International Workshop on Underwater Networks, September 30th - October 1st 2010: Woods Hole, Massachusetts, USA.
We have also committed to sponsor MobiOpp 2012.

Each year, SIGMOBILE is also "in-cooperation" with a number of different events sponsored by other organizations. Events offered "in-cooperation with" SIGMOBILE allow its members to register at the same discounted rate as for members of other sponsoring organizations for the event, providing a significant savings to SIGMOBILE members. During this past year (July 2009 through June 2010), SIGMOBILE was in-cooperation with the following events:

  • MobileHCI 2010: 12th International Conference on Human-Computer Interaction with Mobile Devices and Services. September 7-10th, 2010 in Lisbon, Portugal.
  • Wireless Health 2010, October 4-7th, 2010; Hilton La Jolla Torrey Pines, CA, USA.

In addition to the proceedings for each of the conferences and workshops that SIGMOBILE sponsors, SIGMOBILE also publishes a peer-reviewed, quarterly journal/newsletter for SIGMOBILE members, Mobile Computing and Communications Review (MC2R). Others may also subscribe to MC2R, and MC2R is available in the ACM Digital Library.

The Editor-in-Chief for MC2R is Prof. Suman Banerjee (University of Wisconsin-Madison, USA). The current Area Editors for MC2R are Prof. Aditya Akella (University of Wisconsin-Madison, USA), Prof. Christian Bettstetter (University of Klagenfurt, Germany), Prof. Srdjan Capkun (ETH, Zurich, Switzerland), Prof. Landon Cox (Duke University, USA), Prof. Eylem Ekici (Ohio State University, USA), Prof. Adrian Friday (Lancaster University, UK), Dr. Michelle Gong (Intel, USA) , Prof. Bhaskar Krishnamachari (University of Southern California, USA), Prof. Prashant Krishnamurthy (University of Pittsburgh, USA), Prof. Panos Papadimitratos (EPFL, Switzerland), Prof. Andreas Terzis (Johns Hopkins University, USA), and Prof. Lin Zhong (Rice University, USA). In addition, MC2R currently has two Feature Editors: Dr. Ian Chakeres (The Boeing Company, USA), reporting on activities in the IETF MANET Working Group, and Prof. James C. Lin (The University of Illinois at Chicago, USA), reporting on health aspects of wireless communication.

MC2R publishes articles that provide a balance between state-of-the-art research and practice, with a thorough pre-publication review of every article by experts in the field. Beyond papers reporting the latest research results in all areas related to SIGMOBILE's scope, MC2R keeps the SIGMOBILE community apprised of relevant happenings in the area, by providing regular features on the status of major international mobile computing and communications standards, such as those from IETF, ITU, ISO, and IEEE. The journal also provides a variety of additional resources, such as bibliographies of recent publications in other journals, paper and book reviews, workshop and conference reports, calls for papers, information on research groups throughout the world, bibliographies and locations of technical reports, and other general news in the field.

MC2R places a strong emphasis on quick publication of interesting completed, or work-in-progress technical work; the average turnaround time for papers published in MC2R is about 6 months. Papers in MC2R are selected mainly from an ongoing open call for papers, plus special sections based on conferences and workshops, occasional special topic issues, and some invited papers. The acceptance rate for papers submitted through the open call for papers is quite selective, remaining under about 20%. All aspects of the journal's operation are run entirely by volunteers, including final assembly of each issue.

SIGMOBILE also publishes a monthly E-Mail Newsletter for its members. This electronic newsletter was started in 2004 and is edited by SIGMOBILE's Information Director, Prof. Robert Steele (University of, Sydney, Australia). The newsletter includes SIGMOBILE announcements, pointers to relevant mainstream news articles of interest to SIGMOBILE members, a calendar of upcoming events of interest to our members, and pointers to developer news for active developers in the area of mobile computing and wireless networking.

As an additional resource for our members and the community, SIGMOBILE maintains an extensive web site at, including information about SIGMOBILE and its activities, information about our journal/newsletter MC2R, and information about membership in SIGMOBILE. This web site also contains archived copies of most SIGMOBILE conference web sites, including all previous years of MobiCom, MobiHoc, and MobiSys.

The SIGMOBILE Best Paper Awards are given to the authors of the best paper from among all papers submitted to the conference that year. Typically the conference Technical Program Committee forms the Selection Committee for this award.

At MobiSys 2011, the Best Paper Award was given to two papers: 1) "SignalGuru: Leveraging Mobile Phones for Collaborative Traffic Signal Schedule Advisory" by Emmanouil Koukoumidis, Li-Shiuan Peh, and Margaret Martonosi, and 2) "Chameleon: A Color-Adaptive Web Browser for Mobile OLED Displays" by Mian Dong and L. Zhong. The Best Poster Award went to "You Driving? Talk to You Later" by Hon Lung Chu, Vijay Raman, Jeffrey Shen, Romit Roy Choudhury, Aman Kansal and Victor Bahl. The best Demo Awards were presented to "A System for Aligning Advertisement Delivery with Cellular Base-station Overloads" by Ravi Kokku, Rajesh Mahindra, Sampath Rangarajan and Honghai Zhang, and 2) "Avoiding the Rush Hours; WiFi Energy Management via Traffic Isolation" by Justin Manweiler and Romit Roy Choudhury.

At MobiCom 2010, the Best Paper Award was presented for "The ?-factor: Inferring Protocol Performance Using Inter-Link Reception Correlation", by Kannan Srinivasan, Mayank Jain, Jung Il Choi, Tahir Azim, Edward S. Kim, Philip Levis, and Bhaskar Krishnamachari.

  • Third Place: Dan Levin, Deutsche Telekom Labs "TCPSpeaker: Clean and Dirty Sides of the Same Slate"
At MobiHoc 2011, the Best Paper Award was given to "EM-MAC: A Dynamic Multichannel Energy-Efficient MAC Protocol for Wireless Sensor Networks" by Lei Tang (Rice University), Yanjun Sun (Texas Instruments), Omer Gurewitz (Ben Gurion University), and David B. Johnson (Rice University).

At MobiHoc 2010, the Best Paper Award was given to "Globs in the Primordial Soup: The Emergence of Connected Crowds in Mobile Wireless Networks" by Simon Heimlicher (ETH Zurich) and Kavé Salamatian (Université de Savoie).

At SenSys 2010, the Best Paper Award went to "Design and Evaluation of a Versatile and Efficient Receiver-Initiated Link Layer for Low-Power Wireless.", by Prabal Dutta (University of Michigan), Stephen Dawson-Haggerty (University of California, Berkeley), Yin Chen (Johns Hopkins University), Chieh-Jan (Mike) Liang (Johns Hopkins University), and Andreas Terzis (Johns Hopkins University).

At Ubicomp 2010, the Best Paper Award was given to "ElectriSense: Single-Point Sensing Using EMI for Electrical Event Detection and Classification in the Home", by Sidhant Gupta, Matt Reynolds, and Shwetak Patel (University of Washington).

Finally, SIGMOBILE presented a well deserved 2010 Outstanding Contributions Award to Prof. Mahadev Satyanayanaran (Carnegie Mellon University, USA), for pioneering a wide spectrum of technologies in support of disconnected and weakly connected mobile clients, presented at MobiSys 2011, June 30th, in Washington DC (see MobiSys'11 conference summary).

SIGMOBILE in the News

News Article: "Tag - Your Phone Knows You're It" by Craig Brandhorst in FreeTimes (Columbia's free weekly), Issue: #24 7/19-7/25, featuring a commentary about the MobiSys 2011 paper "TagSense: A Smartphone-based Approach to Automatic Image Tagging" C. Qin (Univ. of South Carolina), X. Bao (Duke Univ.), R. Choudhury (Duke Univ.), S. Nelakuditi (Univ. of South Carolina). It also appeared as a story on the 'Zoom', Polish news website.

Additional Executive Committee Activities

At the request of the ACM publishing group we started working on a Mobility Tech Pack. ACM Tech Packs are "innovative learning packages by subject experts for serious computing professionals", basically an annotated reading list of the most useful papers for students or professionals wanting to enter the field, or refresh their knowledge about the latest significant publications in the area. At the time of writing this report, a draft Tech Pack has been prepared, and should be finalized by the end of Q3 2011.

Last year we established a new Editor-in-chief for MC2R, Prof. Suman Banerjee (Univ. of Wisconsin, Madison, USA), with a fresh agenda and new plans for the publication. At the same time there was a pipeline of prior papers and materials to publish. In the next issue we should see the first results of his planning, and new exciting content for our MC2R publication.

We have investigated adding the independent 'Pervasive Computing' conference to our existing five sponsored conferences, but it has not been a straightforward proposition. The historical advisory committee for Pervasive has been largely composed of European members, and they see less value in moving under the ACM umbrella. The Pervasive 'Town meeting' held at the June 2011 conference in San Francisco generated the following feedback:

  • ~10% would like to move to ACM
  • greater than 50% do not see any advantage and do not care either way
  • a few people see disadvantages
  • it was noted the ACM label does not make a difference for tenure cases in Asia (Korea, Japan), it's only Journals that count.
  • the cost implications were noted (both in terms of overhead and discount for ACM members)
This year the Pervasive and Ubicomp conferences have formed a Joint Steering Committee (JSC) chaired by James Scott (Microsoft Research), and have committed to discussing the issue of sponsorship in that forum. They should make a final decision in the Q3 2011.

In the previous report we had talked about increasing SIG membership by looking for new chapters, creative advertising, or alliances with other SIGs such as SIGOPS. However, little progress has been made on this front. It is much harder that we had previously thought, and will be a subject of on-going discussion. However, it was noted that in terms of revenue, membership is much less significant than profits from our conferences, and monies from the ACM digital library, as a result of licensed readers downloading SIGMOBILE papers.

Our SIGMOBILE Workshop Coordinator, Ahmed Helmy (University of Florida, Gainesville, USA), has recently stepped down after many years of service. As mentioned earlier, we are very grateful for all his contributions, and will now begin a search for a new coordinator. We have successfully found a new chair for the Outstanding Contribution Award (OCA) search committee, Victor Bahl (Microsoft Research), will step down after 15 years of service, and the new Chair will be Edward W. Knightly (Rice University, EDE Dept). We extend many thanks to Victor for his considerable energy in this role, and commitment to maintaining high standards for awarding the OCA since its inception.


Mobile computing is one of the fastest growing subfields within computer science, and as a result SIGMOBILE has become a strong, successful, well-supported organization. Membership is relatively stable, and the SIG's conferences and workshops continue to be well attended, creating a wealth of publications for the ACM digital library, and its members. Moreover, our financial situation has strengthened further in 2011, providing the organization with flexibility and options to support additional high-value programs for the research community in the future.
