Dynamic Ad Hoc Wireless Networks:
From Theory to Practice

What:



A book consisting of original chapters contributed by DAWN researchers, with its
target audience being the academic community and program managers in
funding agencies.
Each chapter addresses some aspect(s) of the research carried out in DAWN, or
the importance and application of “network science.” Edited by JJ & Bob
Why:


We need a publication with larger visibility than scattered papers (even though
they are great papers!) to amplify the impact of our work.
A single reference of salient work done during the first 2+ years of DAWN on the
science of networks and its implications (to DoD and others) is important to the
success of DAWN, but is perhaps even more important beyond DAWN
“Science matters” and “universities leading high-impact research matters.”

How:



14 chapters already being planned, we need to pursue chapters on “needs and
implication,” and we are still soliciting chapters!
Need to work hard to have draft chapters ready by end of the year
Proposal to be submitted to selected publishers (PH & IEEE) with at least a
couple of chapters plus the abstracts and outline of entire book.
