SIGMOBILE FY'09 Annual Report

July 2008 - June 2009
Submitted by: David B. Johnson, SIGMOBILE Chair



ACM SIGMOBILE is the Special Interest Group on Mobility of Systems, Users, Data, and Computing. SIGMOBILE's specialty is mobility. 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 growing membership, healthy finances, well-respected, successful conferences, workshops, and publications, and valuable services for its members and the community.


SIGMOBILE's elected officers consist of its Chair, Vice Chair, Secretary, and Treasurer. The terms in office of the officers over this past year ran from July 1, 2005 through June 30, 2009, and this year, SIGMOBILE held elections for new officers. The outgoing elected officers are Prof. David B. Johnson (Rice University, USA), Chair; Dr. Jason K. Redi (BBN Technologies, USA), Vice Chair; Prof. Chiara Petrioli (University of Rome "La Sapienza," Italy) Secretary; and Prof. Tracy Camp (Colorado School of Mines, USA), Treasurer.

In the SIGMOBILE elections, three candidates ran for Chair, two ran for Vice Chair, two ran for Secretary, and two ran for Treasurer. It is with great pleasure that I announce here the newly elected officers for SIGMOBILE, who took office July 1, 2009:

  • Chair: Dr. Roy Want (Intel, US);
  • Vice Chair: Prof. Robert Steele (University of Sydney, Australia);
  • Secretary: Prof. Ramesh Govindan (University of Southern California, US); and
  • Treasurer: Prof. Lili Qiu (University of Texas at Austin, US).
I hope all SIGMOBILE members will join me in congratulating the incoming new SIGMOBILE officers! I think the SIG will be in great hands as we move forward. I also want to thank all of the candidates for being willing to serve SIGMOBILE and all of the SIGMOBILE members who voted in these elections for letting your voices be heard.

In addition to the elected officers, SIGMOBILE's Executive Committee also includes its Past Chair, now Prof. David B. Johnson (Rice University, USA); and the Editor-in-Chief for SIGMOBILE's journal/newsletter for our members (Mobile Computing and Communications Review or MC2R), Prof. Srikanth Krishnamurthy (University of California, Riverside, USA). SIGMOBILE's leadership also currently includes three appointed positions: Prof. Robert Steele (University of Sydney, Australia), Information Director; Prof. Ahmed Helmy (University of Florida, Gainesville, USA), Workshop Coordinator; and Dr. Guanling Chen (University of Massachusetts Lowell, USA), Digital Library Coordinator.

New Developments This Year

This year, SIGMOBILE began sponsoring the annual Ubicomp conference, the International Conference on Ubiquitous Computing. Held first in 1999 as the International Symposium on Handheld and Ubiquitous Computing (HUC '99), Ubicomp has become the premier forum for novel research contributions that advance the state of the art in the design, development, deployment, evaluation, and understanding of ubiquitous computing systems. Ubiquitous computing is an interdisciplinary field of research and development that utilizes and integrates pervasive, wireless, embedded, wearable and/or mobile technologies to bridge the gaps between the digital and physical worlds. Ubicomp has previously been held as an independent conference; beginning with Ubicomp 2009, Ubicomp is now co-sponsored by ACM SIGMOBILE and SIGCHI.

Also this year, SIGMOBILE provided financial support for CRAWDAD, the Community Resource for Archiving Wireless Data At Dartmouth. CRAWDAD is a wireless network data resource, hosted at Dartmouth College, significantly benefiting SIGMOBILE members and the SIGMOBILE community. CRAWDAD archives wireless trace data from many contributors and develops better tools for collecting, anonymizing, and analyzing the data. This project is important since research in wireless networks has been seriously starved for data; the data archived by CRAWDAD helps us to identify and understand the real problems in wireless networking, to evaluate possible solutions, and to evaluate new applications and services. CRAWDAD was founded in 2005 with support from the NSF CRI program but requires ongoing funding to serve the community. SIGMOBILE is pleased to help support this important initiative.

Likewise this year, SIGMOBILE provided financial support to the Illinois Wireless Summer School, organized by the University of Illinois. The primary target audience for this summer school in wireless networking is graduate and undergraduate students from all universities, and it is also open to faculty and to researchers from industry and government organizations. The topics to be covered include antennas, physical layer issues, wireless networking protocols, wireless security, and wireless standards. This summer school is also supported by NSF, Rockwell Collins, Qualcomm, Microsoft Research, and NEC Laboratories America. The school will be held August 3-7, 2009, at the University of Illinois at Urbana-Champaign; about 190 attendees are currently registered to attend.

Finally, over the past year, SIGMOBILE has gone through the process of revising our Bylaws. The SIGMOBILE Bylaws were originally written when SIGMOBILE was founded in 1996, now 13 years ago, and have not been changed since. Over the years, a number of needed minor changes to them have become apparent. Below is a summary of the changes in these revised Bylaws:

  • Made things gender-neutral (mainly, "Chairman" becomes "Chair").
  • Cleaned up some typos (like a footnote left from some model bylaws that ours were based on 13 years ago).
  • Made it consistent that Secretary and Treasurer are separate positions. This was correct in some places, but other places referred to Secretary-Treasurer as if it were a single position. They have always been separate positions in SIGMOBILE.
  • Removed details of the MobiCom Steering Committee. MobiCom is only one of the five annual conferences SIGMOBILE sponsors or co-sponsors, and details for each conference should be in a separate set of bylaws for that conference, not in the SIG's bylaws.
  • Clarified and updated the statement of our scope.
  • Fixed things to conform to changes in ACM in the 13 years since our original SIGMOBILE Bylaws were written.
After submitting the revised SIGMOBILE Bylaws to ACM in March, from April through May, voting on them among the members of the ACM SIG Governing Board Executive Committee (SGB EC) took place. After receiving unanimous approval from the SGB EC, SIGMOBILE members were given the opportunity to raise any objections to the proposed revised Bylaws. On June 11, after receiving no objections from SIGMOBILE members, the revised Bylaws were submitted to the ACM Executive Committee, which approved the changes effective July 22, 2009.

Campbell (Dartmouth College, USA) was featured in a June 22, 2009 article on the Technology Review magazine web site ( This article, "Cell Phones That Listen and Learn: New software tracks a user's behavior by monitoring everyday sounds," summarizes the work and points out that it was presented in a paper at MobiSys this year. This research and the MobiSys presentation were also featured in a July 10 posting on Slashdot entitled "Cell Phones That Learn the Sounds of Your Life" (

MobiSys 2010 is being planned for June 2010 in Palo Alto, California, USA.

In addition to the conferences and co-located workshops above, SIGMOBILE also sponsors the HotMobile (previously known as WMCSA) workshop 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. This workshop was previously sponsored each year by the IEEE Computer Society but has been sponsored instead by SIGMOBILE since HotMobile 2008.

HotMobile 2009, the 10th Workshop on Mobile Computing Systems and Applications, was held February 23-24, 2009, in Santa Cruz, California, USA. Dr. April Slayden Mitchell (Hewlett-Packard Labs, US) served as the General Chair, and Prof. Jason Hong (Carnegie Mellon University, USA) served as the Program Chair. The HotMobile 2008 technical program featured a keynote talk by Dr. Bob Iannucci (Senior Vice President and special technology advisor, Nokia Corporation, USA). HotMobile 2009 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.

HotMobile 2010 will be held February 22-23, 2010, in Annapolis, Maryland, USA.

SIGMOBILE continues to be fortunate to receive strong support for its conferences and workshops from leading-edge companies and organizations from around the world. This year, the organizations that have contributed to SIGMOBILE conferences and workshops, helping to ensure their success, include Arch Rock, Cisco, the Cooperating Objects Network of Excellence, Crossbow Technology, Daimler, Dartmouth College Institute for Security Technology Studies, GM, Hewlett-Packard, IBM, Intel, Istituto di Informatica e Telematica, Madison Ventures, Microsoft Research, NEC Laboratories America, NSF, Nokia, and PARC. SIGMOBILE sincerely thanks each of them for their support.

Each year, SIGMOBILE is also "in-cooperation" with a number of different events sponsored by other organizations. Events offered "in-cooperation with" SIGMOBILE allow SIGMOBILE 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 2008 through June 2009), SIGMOBILE was in-cooperation with the following events:

She presented her Athena Lecture, entitled "Wireless Sensing Systems: From Ecosystems to Human Systems," at MobiCom 2006. SIGMOBILE congratulates Deborah on her continued success with her election this year to the National Academy of Engineering!

Future Challenges

Throughout most of SIGMOBILE's history, our membership has continued to grow steadily. Last year, however, it had begun to look like this trend had slowed or slightly reversed, joining the trend experienced by most other SIGs in having declining membership. I am happy to report, however, that any decline has now reversed, with SIGMOBILE's membership growing about 5% this year. We have been attempting to better promote, particularly among conference attendees, the value of SIGMOBILE membership — and the affordability of SIGMOBILE membership. It is too early to tell if this campaign is really working, and we will continue to monitor trends in SIGMOBILE membership, but we are encouraged by the latest membership numbers. We will also continue to look for additional ways to serve our members and to encourage the many researchers, practitioners, users, students, and others in the broader community to join SIGMOBILE.

Another challenge for the future is the effect on conference attendance of three different concerns expressed by some in our community and beyond. First, given concerns over the state of the economy, now and in the future, some potential conference attendees may be scaling back on the amount of travel they can include in their budgets. Second, given the increased security measures introduced in all aspects of travel, including security screening and baggage handling inconveniences at airports and new restrictions and increased processing times required in obtaining visas, some potential conference attendees may be questioning whether to attend conferences or may be unable to attend. Third, given increased concerns about the environment and the "carbon footprint" of travel, some potential conference attendees may begin opting to avoid the travel to conferences and to only read the proceedings electronically afterwards. It is unclear the extent to which any of these concerns have affected conference attendance currently, but the number of times different members in our community have raised these issues with me continues to increase.


SIGMOBILE continues to be a strong, successful SIG. Our conferences, workshops, and publications are well respected and well supported, our finances are healthy, and our membership is growing and active. This is my last annual report here, as my term as SIGMOBILE Chair has ended. But it is with great confidence that I pass the leadership of SIGMOBILE on to the newly elected SIGMOBILE Chair and the other newly elected SIGMOBILE officers. Congratulations again to Roy, Robert, Ramesh, and Lili on their election. I'm sure SIGMOBILE will be in good hands as we move forward.
