IPSN 2016 PhD Forum

The Ph.D. Forum at the 15th ACM/IEEE Int. Conference on Information Processing in Sensor Network (IPSN, co-located with CPSWEEK) provides an opportunity for Ph.D. students to present their work in progress to the scientific community and obtain individual feedback from leading researchers in the field.
The Forum will be structured as a series of short presentations by the students, followed by collective discussions. The student presentations will be interleaved with speeches by leading researchers, who will provide their perspectives on current and future research in the field, as well as on how to best pursue a Ph.D. in this context. A “speed mentoring” session will conclude the Forum to let the students obtain individual feedback and advice.
Participating students will also have the opportunity to present a poster during the main conference to leverage further interaction with CPSWEEK attendees.
Current Ph.D. students in the early stages of their career are encouraged to submit a 2-page abstract about their on-going research to be considered for the Ph.D. Forum. The abstract shall also include a one-paragraph bio, along with brief information on how long the student has been in Ph.D. school and the expected time until graduation. The student should be the *sole* author although contributions of the adviser and others should be acknowledged. The presentation at the Forum and the poster at the conference will be considered for a “Best Research Proposal” award. The Ph.D. Forum abstracts will also be part of the official IPSN proceedings.
Submissions will be reviewed by the Ph.D. Forum committee to ensure quality, relevance, and potential benefit from attendance to the Forum. Authors of accepted submissions are expected to participate in person in the Forum – to be held on April 11th, 2016 – and to present a poster both at the Forum and at the main conference. There will be no separate registration fee for the Forum. Participating students will only need to register to the main IPSN conference.
For any questions, please contact Luca Mottola <luca.mottola -AT- polimi -dot- it> or refer to the IPSN PhD Forum group on Facebook.

Low-Power Wireless Bus (LWB)

We are happy to announce the open-source release of the Low-power Wireless Bus (LWB), a communication protocol for low-power wireless embedded systems. By mapping all communication onto network-wide Glossy floods, LWB lets low-power wireless nodes communicate as if they were connected to a shared bus, thus hiding the complexity of the underlying multi-hop topology from upper layers.

You may find the LWB and Glossy code on https://github.com/ETHZ-TEC/LWB including instructions on running an LWB demo application. We also outline the current code status and layout and provide references for further reading.

The system includes a revised implementation of LWB as described in the original SenSys’12 paper, based on a minimal subset of Contiki. While LWB itself is mostly platform-independent, the underlying Glossy code is platform-specific. There is a new port of Glossy for the CC430 SoC platform, which features an 868/915 MHz radio and an MSP430 microcontroller on one chip. In the future, we intend to incorporate also the first Glossy port for the TelosB platform. In the meantime, you may find this port at http://sourceforge.net/p/contikiprojects/code/HEAD/tree/ethz.ch/glossy/

We would like to invite the community to check out the code and to get in touch with us if you have comments, suggestions, bug reports, or would like to get involved and submit your code contributions to LWB and Glossy. We particularly welcome the contribution of Glossy ports to other state-of-the-art platforms.

SENSYS 14 Doctoral Colloquium

The SenSys 2014 Doctoral Colloquium seeks to provide a friendly, supportive, and constructive environment where PhD students can present their research in progress for an open discussion guided by a panel of experienced researchers and practitioners.

The DC will be structured as a series of short presentations by the students followed by individual discussions, feedback, and advise. The student presentations will be interleaved with speeches by leading researchers, who will provide their own perspectives on current and future research trends in networked sensing, as well as on how to best purse a Ph.D. in this field. Participating students will also have the opportunity to present a poster during the main conference to leverage further interaction with SENSYS attendees.

Important Dates:
Submission deadline: September 2nd, 2014
Notification of acceptance: September 15th, 2014
Ph.D. Forum: November 6th, 2014

A Decade of TinyOS Development

OSDI 2012 has an interesting paper on the evolution of TinyOS over the past 10+ years. It looks at both technical and social decisions that contributed to the success of TinyOS. The paper also looks back and evaluates what worked, what didn’t, and why. It’s rare to see papers at technical conferences talking about the non-technical aspects of large software development projects, so should be an interesting read. You can find the paper here.

Researchers Boost Efficiency of Multi-Hop Wireless Networks

Multi-hop wireless networks can provide data access for large and unconventional spaces, but they have long faced significant limits on the amount of data they can transmit. Now researchers from North Carolina State University have developed a more efficient data transmission approach that can boost the amount of data the networks can transmit by 20 to 80 percent.

“Our approach increases the average amount of data that can be transmitted within the network by at least 20 percent for networks with randomly placed nodes – and up to 80 percent if the nodes are positioned in clusters within the network,” says Dr. Rudra Dutta, an associate professor of computer science at NC State and co-author of a paper on the research. The approach also makes the network more energy efficient, which can extend the lifetime of the network if the nodes are battery-powered.

Multi-hop wireless networks utilize multiple wireless nodes to provide coverage to a large area by forwarding and receiving data wirelessly between the nodes. However, these networks have “hot spots” – places in the network where multiple wireless transmissions can interfere with each other. This limits how quickly the network can transfer data, because the nodes have to take turns transmitting data at these congested points.

Data can be transmitted at low power over short distances, which limits the degree of interference with other nodes. But this approach means that the data may have to be transmitted through many nodes before reaching its final destination. Or, data can be transmitted at high power, which means the data can be sent further and more quickly – but the powerful transmission may interfere with transmissions from many other nodes.

Dutta and Ph.D. student Parth Pathak developed an approach called centrality-based power control to address the problem. Their approach uses an algorithm that instructs each node in the network on how much power to use for each transmission depending on its final destination.

The algorithm optimizes system efficiency by determining when a powerful transmission is worth the added signal disruption, and when less powerful transmissions are needed.

The paper, “Centrality-based power control for hot-spot mitigation in multi-hop wireless networks,” is published online by the journalComputer Communications, and is in press for a print version of an upcoming issue of the journal. Pathak is lead author. The research was supported in part by the U.S. Army Research Office.

The World is increasingly experiencing a strong need for energy consumption reduction and a need for efficient use of scarce natural resources. Official studies report that buildings account for the largest portion of World’s energy expenditure and have the fastest growth rate. Wireless sensor networks (WSNs) play a key role in enabling energy-saving systems in buildings and surrounding spaces by providing a reliable, cost-effective and extensible solution that can be placed in existing as well as new structures and can be controlled via the Internet.

Important Dates
* Paper submission deadline: July 30, 2011
* Notification of acceptance: August 31, 2011
* Camera Ready Due: September 15, 2011
* Workshop date: November 1, 2011

*** New this year: Demo session! ***

We solicit both papers AND demos that focus on new techniques and technologies capable of improving the global energy efficiency of buildings leveraging connected sensing systems, networks, and devices. Technical papers will be presented on November 1, 2011, and the demo session will be co-located with ACM SenSys on November 3, 2011.
