Place: Auditorium B210E/B211E Meeting Room,
San Diego Supercomputer Center, UCSD Campus, La Jolla, CA
This year, we want to explore existing capabilities and potential opportunities for network measurement in the wireless domain, and research infrastructure to support it. One motivation is the increasing attention to measuring the character of broadband access, including the U.S. FCC Measuring Broadband America effort (for both wireline and wireless connectivity). The more complex structure of cellular access, with its signalling protocols and potential to shape different sorts of application traffic, makes it harder to decide what to measure in order to characterize or compare wireless service.
Our goals for this two day workshop are: (1) to understand the wireless research infrastructure landscape(s), and measurement capabilities that support (or should support) it; (2) to determine what are the important questions that measurement can help answer who will be the customer for the measurements; and (3) to propose a vision/roadmap for wireless measurement research infrastructure and activities for the next decade. Key topics to be discussed include:
- research infrastructure to support mobile/wireless measurement
- review existing wireless research infrastructures
- what specific questions are being investigated with current wireless measurement research activities?
- what large-scale data respositories of wireless measurements exist and how are they used?
- who is funding work in this space?
- what does the research community need? who can help?
- mobile/wireless measurement capabilities/tools
- articulate what we can measure about wired and wireless networks from today's mobile devices, e.g., signal strength, coverage, performance, including latency (bufferbloat) and throughput (and relationship to QoE measurements), spectrum utilization, network topology, control signaling overhead, (device) energy usage, cross-layer measurements
- compare priorities and capabilities across different wireless media and protocol layers
- measurement from the edge
- how much measurement is occuring internal to commercial networks, for operational purposes or as part of developing new technology?
- which measurement questions are important to different parts of the ecosystem: carrier, consumer, regulator?
- incentives to deploy tools
- incentives to get enough people or the right people to deploy tools
- identification and mediation of privacy issues in mobile/wireless measurements
- incentives to share data
- monitoring spectrum usage
- what technologies, tools, or activities exist to support monitoring usage of emerging shared spectrum, e.g., whitespaces.
- how do operators of databases maintaining spectrum utilization information validate their data?
- how is the data being used or how could it be used?
- discuss opportunities for validation of mobile measurements of various types
- how much validation is happening/possible today?
Unlike a traditional workshop where attendees present talks on their work, we will have a series of sessions on the pre-selected topics with presenters preparing short talks and subsequent discussion. Not everyone necessarily gives a talk, but everyone would be expected to participate in the discussions. This format lets us dig deeper into the selected topics so that we can try to develop some consensus on a wireless measurement research agenda that may require concerted infrastructure investment.
All talks are 10 minutes long (unless indicated otherwise), plus 5 minutes for questions after each talk. Additionally, the following ground rules apply for all talks:
- include one slide on data sharing
- include one slide on visualization of data (extra credit)
- last slide: what you want to get from the audience / workshop
To generate discussion and to orient other participants to your talk, please send a URL or a PDF to firstname.lastname@example.org of something you'd like the audience to have read before your talk. This can be any of:
- a related URL that inspires your research
- a related URL detailing your research
- a URL related to your talk that you consider worth other participants' time to look over
- a recent blog entry or article so people can get an idea of who you are
- the actual PDF slideset which you'll be presenting

Local Arrangements / Getting to UCSD
For this workshop, attendees are expected to make their own hotel reservations and transportation arrangements from their hotels to the workshop. For CAIDA's list of local hotels including shuttle availability, see the updated Local Hotels list (PDF). Contact the hotel directly for hotel shuttle schedules (if available) to the San Diego Supercomputer Center (SDSC).
This workshop is being held in the SDSC East Auditorium (Room B210E/B211E) that faces Hopkins Drive.
(For those GPS-enabled attendees, the GPS coordinates near the SDSC Auditorium is WGS84: 32°53'03.77"N, 117°14'20.31"W)
General driving directions to SDSC are located on the CAIDA Contact and Visitor Info page.
- Parking on campus
The most convenient parking is in the Hopkins parking structure at Hopkins Dr and Voigt Dr, just south of SDSC.
Parking Permits: Parking permits are required to park on UCSD Campus. On arrival to campus on the morning of Day 1, check in with a CAIDA staff member at the small turn-in driveway in front of the stairs of the SDSC building on Hopkins Drive. We will give you a parking permit for the day, and then point you to the Hopkins Parking Structure for parking.
Parking permits for subsequent days will be provided at the end of Day 1, just prior to the Reception.
After picking up your parking permit, it is recommended you go to the Hopkins Parking Structure next to SDSC and park on the lower levels. Walk back the way you came out of the bottom of the parking garage (level 2), and back to the stairs of the SDSC building. The auditorium is on the left just before the stairs, labeled Auditorium or B210E/B211E Meeting Room.
The AIMS 2014 workshop will be held in the SDSC Auditorium.
For transportation concerns, general questions and help, contact Cindy Wong at <cindy at caida.org> or (858) 534-5109.
