INTEL-NTU Connected Context Center September 2011 Monthly Report
Project: Cooperative Information Fusion and Inference (CIFI) in SIGARC
PI: Professor Kwang-Cheng Chen
INTEL Champion: Dr. Kerstin Johnsson and Dr. Yen-Kuang Chen
1. Team Members
Post-Doc Researcher: expecting to join in September
Research Assistants1: Wen Chon Ao, Sung-Yin Shih (start from September 1),
Farming Tseng (start from September 1)
PhD Students: Tzu-Yu Chuang,
MS Students: Howard Peng, David Liao, Christina Yin (summer visiting student
from UCLA)
2. Discussion with Champion
In this month, discussions are on the future directions of CIFI. Technical
challenges on fusion-assisted traffic reduction research have been mentioned
and discussed. In addition to theoretical approach, we should try some
algorithmic approaches.
3. Progress
Current research of project CIFI focuses on grounding technology development
and explorations. A few key issues are actively studied in July and August:
 Spectrum map: We focus on applying compressed sensing to construct the
spectrum map and tradeoff to achieve this purpose by considering
communication resource overhead. In this month, efforts are on polishing
manuscript for publication.
 Techniques to assist routing: Project CIFI can be viewed as networking
technology in the swarm part of cyber physical systems. We are looking
into the meaning of cooperation in communications and networks. In
addition to traditional local view to study connectivity and degree
distribution under interference-limited wireless networks, we are trying
to develop a global view on this subject that has never been investigated
in literatures. We wish this to possibly be the world leading research. As
the first step, we are working on a meaningful experiment to demonstrate
our idea through evolutionary game theory, based on the architecture of
networks.
 Routing: Based on the architecture concept and background study, we are
starting to develop routing from local view and global view, as unlikely
for one single algorithm to work in a universal environment.

4. Brief Plan for Next Month
In the following month, we shall continue to study dynamics of spectrum sharing
wireless networks, and to develop spectrum-map based routing algorithms.
5. Research Byproducts
The following papers related to project CIFI have been published in the IEEE
Transactions on Vehicular Technology (NTU and Center’s Outstanding Journal)
since last report. This is a joint international (Singapore, Taiwan, US, Germany)
effort to provide an overview of various technologies on cognitive radio
networks, a major form of spectrum sharing wireless networks that is one of the
major efforts in project CIFI). The first 3 authors are IEEE Fellows, and Liang, KC,
Mahonen are among top active authors in this research according to IEEE Xplore.
Y.C. Liang, K.C. Chen, J. Y. Li, P. Mahonen, “Cognitive Radio Networking and
Communications: An Overview”, to appear in the IEEE Transaction on Vehicular
Technology, vol. 60, no. 7, pp. 3386-3407, Sep 2011. 8th top accessed article in
June 2011, 2nd in July 2011 (ranking in August is not known at this moment, but
the situation is unusual as paper being published in September)
The PI also attended the IEEE PIMRC 2011 (9/12-14, top conference in SIGARC)
to present 3 papers (2 related to green wireless communications and 1 related to
wireless optical communications). These papers, though not related to project
CIFI, are related to other projects in SIGARC. PI also visited Princeton University
to discuss with Prof. Poor, Dean, Engineering and Applied Science, regarding
future research cooperation.
In 2011, counting papers in the IEEE GLOBECOM 2011, there will be 11+1 top
IEEE conference papers (due to one paper about security) from Project CIFI in
2012 as a fruitful year: 1 IEEE VTC, 2 IEEE INFOCOM, 1 IEEE ICC, 7+1 IEEE
GLOBECOM.
