A “Science of Networking” fundamental limits logic analytical models Lower-bound Upper-bound simulations APPLICATION collaborative applications… TRANSPORT end-to-end transport protocols… NETWORK routing-structure maintenance opportunistic packet forwarding interconnection LINK synchronization transmission scheduling neighborhood discovery PHYSICAL Antennas, radios protocols and architectures Technical Approach What is the performance of specific protocols with a specific PHY? What is the best that we can possibly do? Is the protocol correct?

  8. Summary of Scientific Progress Recognized Technical Leadership: • Ephremides (Maryland): Invited plenary talk at the Information Theory Workshop in Porto, Portugal, May, 2008 • Imvited plenary talk at the WPMC in Lapland, September 2008. • J.J. Garcia-Luna-Aceves (UCSC): General Chair, MobiCom 2007 • Andrea Goldsmith (Stanford): President-Elect: IEEE Information Theory Society (for 2009) Stanford Postdoc Mentoring Award. • Muriel Medard (MIT): 2007 Gilbreth Lectureship from the National Academy of Engineering Elected a Fellow of the IEEE • Pravin Varaiya (UCB): 2008 AACC Richard E. Bellman Control Heritage Award Honorary Doctorate, Technical University of Crete

  9. Summary of Scientific Progress • New fundamental results on the capacity of wireless networks. • 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 and testing

  10. 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.
