C A L L F O R P A P E R S
QPWSN’10
1st International Workshop on "QoS Provision in Wireless Sensor Networks"
http://www.icte.uowm.gr/qpwsn10/
organized in conjunction with
The 6th IEEE International Conference on Distributed Computing in Sensor Systems (DCOSS '10)
23 June 2010, Santa Barbara, California
Important Dates:
Manuscript Submission: 23 April 2010
Acceptance Notification: 7 May 2010
Camera ready: 21 May 2010
Scope and Overview:
Wireless Sensor Networks (WSNs) are a modern kind of wireless networks, where numerous monitoring devices are interconnected to communicate their collected data. The literature has not paid yet enough attention to QoS in WSNs. This is mainly due to the currently unclear purpose and usage of the WSNs, which significantly differ from the traditional networks. However, modern WSN applications require traffic differentiation, guaranteed end-to-end delivery, low delay jitter, and high throughput. The sensors’ limited resources and energy autonomy combined with the unreliable wireless medium make QoS support in WSN certainly challenging. Thus, new designs for offering QoS in WSNs are becoming necessary.
This Workshop will try to analyze modern methods of providing QoS support in WSNs, explain all related issues, highlight the problems that arise when trying to provide QoS demanding services over wireless networks, present the theoretical background, bring out related solutions given so far, and moreover, exhibit the latest research concepts and relevant ideas regarding near-future implementations.
Topics of Interest:
Topics of interest include, but are not limited to:
- Multimedia transmissions over WSNs
- QoS capable routing algorithms for WSNs
- Traffic prioritization schemes for WSNs
- QoS supportive protocols for medium access control in WSNs
- Power saving mechanisms for WSNs
- Medical content transfer using sensors for telemedicine
- Categorized data communications over environment monitoring WSNs
- Novel applications for QoS aware WSNs
- Cross-layer techniques for QoS provision in WSNs
- Simulation of QoS aware WSNs
- Analytical models for QoS aware WSNs

CFP: MST Journal Special Issue on WSN: Designing for Real World Deployment
Call for papers
Measurement Science and Technology Journal (Institute of Physics)
Special Issue on
Wireless Sensor Networks: Designing for Real-World Deployment and
Deployment Experiences
A vast number of protocols, architectures and design methods for
Wireless Sensor Networks (WSNs) have been proposed within the last
decade. Analytical methods, simulation tools and laboratory
experimentation were used to validate the proposals and demonstrate
that the solutions put forth should work as expected. However, many
such solutions failed (and sometimes quite dramatically) when deployed
in a real-world application context. This is often the consequence of
making ill-informed assumptions about the environment in which the WSN
will be deployed, lack of attention to specific conditions that will
be encountered in the deployment and incomplete application
specification. In addition, good solutions for many important
real-world deployment problems are missing. For example, mechanisms
for dealing with missing data, in-network debugging tools or fault
management strategies for real deployments are required.
This special issue has several aims:
· to collect insights from real-world deployment efforts that can
help the WSN community to better understand the issues needed to be
accounted for when designing WSN protocols, architectures and
algorithms;
· to document particular real-world deployment issues encountered
by practical scientists and highlight more generic WSN solutions and
tools born from practical, deployment experience;
· to report on WSN protocols and mechanisms that have had, in the
past, only a theoretical treatment but have recently been proven to
work well in real-world deployments.
We are seeking contributions describing innovative work in the realm
of real-world WSN deployments. Topics of interest include, but are not
limited to:
· Issues with deployment assumptions: setting realistic
application requirements; user interaction with the WSN design process
and with the end systems; the use of communication channel and sensor
and sensing models; experiences with communication protocols, energy
management and expected network lifetime; in-network processing;
real-time issues in deployed systems; effective information extraction
strategies.
· Supporting tools and methods for real-world deployment:
deployment and debugging tools; on-the fly programming, configuration
and installation support; management of deployed sensor networks;
security, availability and dependability issues in sensor networks;
fault-tolerance and troubleshooting sensor networks; network health
monitoring and management; practical medium access control protocols;
topology control and routing protocols in real-world deployments;
practical localization and time synchronization.
· Novel real-life WSN applications: deployment success stories
leading to technology adoption; failure stories leading to iterative
hw/sw developments and re-deployment; novel measurement instruments
based on WSNs.
Notes for Prospective Authors: The scope of this call is restricted to
work that falls within the remit of the MST Journal. Articles should
bring forth new WSN based measurement techniques and systems,
significant improvements to existing measurement techniques or
describe the application of existing techniques in novel situations.
Submitted papers should not have been previously published nor be
currently under consideration for publication elsewhere. Expanded,
archival versions of papers delivered at technical conferences are
welcomed.

Sensors to Help You Get Fit - From Nike, Adidas & Others: "
Discuss
"
Keep up, because tracking your fitness progress on the Internet - via sensors attached to your body or workout gear - is going to become very popular.
Sponsor
The Nike+ shoes come with a sensor that tracks your run, then sends the data to your iPod. It even has its own social network. And what Web product circa 2010 doesn't come with a Twitter and Facebook connection? Sure enough, the Nike+ can automatically tweet and post a status report on Facebook.
The miCoach Pacer can also verbally coach the runner during their run, "to ensure that they are staying within their targeted heart rate zone."
There's an accompanying website, where users can create training plans, set goals and monitor their progress.
Let us know if you currently use an Internet-connected fitness system, especially if it makes use of sensors.

Highlights from EWSN 2010
Highlights from EWSN 2010: "I was invited to give the keynote speech at the European Wireless Sensor Networks conference in Coimbra, Portugal. This was a fantastic location for a conference -- Coimbra has one of the oldest universities in Europe, over 700 years old. It's a beautiful city. EWSN is the European counterpart to conferences such as SenSys and IPSN. It is a very different crowd than typically attends those events. I learned a lot about a couple of the big EU-sponsored sensor nets projects including CoNet and GINSENG. Interestingly, the Contiki OS seems to be pretty popular amongst the European research groups, in contrast to the TinyOS-dominated US landscape.
My keynote was entitled 'The Next Decade of Sensor Networking' and I tried to argue that the field is running the risk of becoming stagnant unless we define some big research challenges that will carry us for the next decade. I've blogged about these themes here before. I delivered the talk in 'Larry Lessig' style -- having written the 'script' as an essay and then making slides to highlight the key points, rather than starting with the slides and ad libbing the voiceover as I usually do. I'll post a video here soon - the slides are more than 50 MB and don't really go well on their own.
A couple of highlights from the conference, though I had to miss the last day.
Jayant Gupchup from Johns Hopkins gave a talk on Phoenix, an approach to reconstructing the timestamps for sensor data after the fact. The idea is to not use a time synchronization protocol, but rather have nodes log enough data that can be used for post-hoc time correction. This is an interesting problem that was motivated by their experiences running sensor nets for more than a year, in which they observed a lot of node reboots (which throw off simple timing approaches) and extended periods when there was no suitable global timebase. The Phoenix approach collects information on nodes' local timestamps and beacons from GPS-enabled nodes at the base station, and performs a time rectification technique, similar to the one we developed for correcting our volcano sensor network data. Phoenix achieves around a 1 sec data accuracy (which is acceptable for environmental monitoring) even when the GPS clock source is offline for a significant period of time.
Raghu Ganti from UIUC gave a talk on 'Privacy Preserving Reconstruction of Multidimensional Data Maps in Vehicular Participatory Sensing.' The title is a bit unwieldy, but the idea is to reconstruct aggregate statistics from a large number of users reporting individual sensor data, such as their vehicle speed and location. The problem is that users don't want to report their true speed and location, but we still want the ability to generate aggregate statistics such as the mean speed on a given road. Their approach is to add noise to each user's data according to a model that would make it difficult for an attacker to recover the user's original data. They make use of the E-M algorithm to estimate the density distribution of the data in aggregate.
Although the paper considered a number of attacks against the scheme, I was left wondering about a simple binary revelation of whether a user had recently left their home (similar to PleaseRobMe.com). One solution is to delay the data reporting, although one would be able to learn the approximate time that an individual was likely to leave home each day. The other approach is to perturb the timing data as well, but this would seem to interfere with the ability to ask questions about, say, traffic levels at certain times of day.
Finally, Christos Koninis from the University of Patras gave a talk on federating sensor network testbeds over the Internet, allowing one to run testbed experiments across multiple testbeds simultaneously, with 'virtual' radio links between nodes on different testbeds. So you could combine a run on our MoteLab testbed (around 190 nodes) with the TWIST testbed (220 nodes) to get a virtual testbed of more than 400 nodes. This is a very cool idea and potentially extremely useful for doing larger-scale sensor net experiments. Their approach involves routing data over a node's serial port through a gateway server to the other end where it is injected into the destination testbed at the appropriate point. They can emulate a given packet loss across each virtual link, not unlike Emulab. Unfortunately they did not really consider making the cross-testbed packet transmission timings realistic, so it would be difficult to use this approach to evaluate a MAC protocol or time sync protocol. It also does not properly emulate RF interference, but I think this is still a very interesting and useful ideas. Another cool aspect of this project is that they can add virtual simulated nodes to the test
bed, allowing one to run mixed-mode experiments.

Unfortunately they did not really consider making the cross-testbed packet transmission timings realistic, so it would be difficult to use this approach to evaluate a MAC protocol or time sync protocol. It also does not properly emulate RF interference, but I think this is still a very interesting and useful ideas. Another cool aspect of this project is that they can add virtual simulated nodes to the test
bed, allowing one to run mixed-mode experiments.

Zigbee Network Layer Tutorial - Part 3: Broadcasts and Neighbors
Zigbee Network Layer Tutorial - Part 3: Broadcasts and Neighbors: "I thought I would spend this portion of the series discussing some of the more detailed parts of the data path. Since the tree (index.php/Articles/Zigbee/Zigbee-Tree-Routing-How-It-Works-and-Why-It-Sucks.html) and mesh (index.php/Articles/Zigbee/zigbee-mesh-routing-interactive-tutorial.html) routing is already explained in other articles, I’d like to talk about the other two forwarding methods: broadcasting and the neighbor table. For those new to the Zigbee spec and trying to implement the broadcast functionality, it can be pretty confusing. At least it was for me when I had..."
Zigbee Network Layer Tutorial - Part 2: The Rx Data Path
Zigbee Network Layer Tutorial - Part 2: The Rx Data Path: "I left off last time explaining the transmit data path side of the Zigbee networking layer. The receive data path is fairly similar, but there are some minor complications. When a frame arrives over the air, the radio driver will take it out of the buffer and store it somewhere. It should then signal the next higher layer (in this case the MAC) to retrieve the frame. Incidentally, this part of incoming data handling is common to just about every..."
Zigbee Network Layer Tutorial - Part 1: The Tx Data Path
Zigbee Network Layer Tutorial - Part 1: The Tx Data Path: "I've been meaning to get around to this for a while now, but things have been so busy that I just haven't had the time. Or maybe I was just too lazy. In any case, today is a good time to kick off a series detailing the Zigbee NWK layer, mostly because I caught a cold and it pretty much rendered me useless for any heavy thinking. I know it's a bit late to start a series on the..."
