2. Discussion with Champion
Discussion of future plan for the project.
3. Progress
Current research of project CIFI focuses on grounding technology development
and explorations. A few key issues are actively explored:
 Explore to identify bottlenecks of realizing large ad hoc network and to
enable fundamental scalability of ad hoc networking, under wireless
fading links and basic operating algorithms. Current focus is to compile
various results and to write into an article.
 System dynamics: Leverage prey-predator modeling from mathematical
biology from nature resource sharing, we install ALOHA and conduct
precise finite-user throughput-delay analysis and stabilization, and
operating conditions from system dynamics, under consideration of
network graph (i.e. connections among nodes) in addition to practical
operation errors.
 We are exploring the true meaning of cooperation via game theory and
stochastic geometry. We investigate in general ad hoc networks and onehop relay and more in-depth study. We obtain the conditions to execute
cooperative relay in wireless networks, which is different from people’s
belief in a decade since the innovation of cooperation into
communication. More detailed formulation is under way. In the mean
time, we also reconsider for cooperative sensing in networks, and develop
the geometric approach to design the system, particularly radio resource
allocation and power control.
4. Brief Plan for Next Month
In the following month, we shall try to continue the directions.

5. Research Byproducts
In this month, we presented a paper in the top conference, IEEE International
Conference on Communications (ICC), Budapest, 2013.
C.Y. Kao, W.C. Ao, K.C. Chen, Spatial Distributed Dynamic Spectrum Access”, IEEE
International Conference on Communications, Budapest, 2013. This paper
presents spectrum access strategy and results violating intuition for spectrum
sharing ad hoc networks, via stochastic geometry and game theory.
In addition, PI was invited to give a keynote speech in an international
conference and as a speaker in a plenary panel in another top conference (IEEE
VTC – Spring).
[1] “Some Open Problems in Cognitive Radio Networks”, Cognitive Radio
Systems and Networks for Flexible Spectrum Usage, IEEE Vehicular
Technology Conference – Spring, Dresden, 2013. Presenting research
challenges and potential solutions in spectrum sharing ad hoc networks.
[2] “Statistical Communication Theory 3.0 in Cyber World”, 16th International
Wireless Personal Multimedia Communications Conference, Atlantic City,
2013. Presenting the evolution of communication theory and its revolution
potential to big networked data analysis and inference, through multiuser
detection and sensor information fusion (as one core of project CIFI). This
work was done when PI taking sabbatical at MIT.
PI also delivered an invited talk as follows. Prof. Barabasi has citations around
100K and h-index around 100, and is considered as the pioneer in network
science (big data is one major application in network science). He has authored
50-100 or so publications in Science, Nature, and Cell (the only 3 top journals at
NTU) since breaking-through article published in Science in 1999.
“Network Science and Wireless Networks”, Center for Complex Network
Research, Northeastern University (also known as Barabasi Lab.), Boston, 2013.
This talk links CIFI project results to network science. Prof. Barabasi particularly
raised a research cooperation opportunity in communication networking with
project CIFI, in a private conversation after his attending my talk.
