Summary of Scientific Progress 5/19/2018 Summary of Scientific Progress New fundamental results on the capacity of wireless networks (MPR, heterogeneous information dissemination, multi-channel). Novel ideas on the effect and practical use of network coding in ad hoc networks New analytical models of the performance of various communication protocols New results on cross-layer interaction and optimization Novel approaches to routing in connected and disconnected wireless networks New approaches to information dissemination New techniques for large-scale simulations

Dynamic Ad Hoc Wireless Networks: From Theory to Practice 5/19/2018 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.
