					             CSE802.11

           Summer Readings on
Wireless, Ad-hoc, Mobility, Power, Energy…
              Why Wireless?
+   One of the top 3 fastest growing techonology
    areas wrt stock growth
+   Wireless broadband revenue will grow
    140%/year for the next 5 years
+   Gates: “Mobility will be the fastest growing MS
    business”
+   Mobicom ranks 5th on CiteSeer’s “Estimated
    Impact” above Sosp, Popl, Siggraph, Sigmod,
    Tocs….
                     Goal
• Educate ourselves in the area
  – basic vocabulary, problems, areas of research,
    future directions
• Spark discussion, interest, research(?)

• We can’t afford to ignore wireless!!
                   Format
• Typical 590 seminar:
  – Presenter signs up today
  – Reads the papers
  – Sends an e-mail 1 week before pointing out
    paper to be read
  – Presentation/Debate/Discussion
                 CSE 802.11
• Based on a list of papers compiled by Victor Bahl
  for a similar reading group at MSR
• Lots of papers and topics removed
   – Short and Sweet
• New papers included
• External Presenters:
   – Jay Lorch (Berkeley, MSR)
   – Jitu Padhye (UMass, ACIRI, MSR)
• External Participation:

       •   dynamic source routing
       •   ad hoc on demand distance vector
   – Paper on GPSR – greedy perimeter stateless routing
              Weeks 6, 7 and 8
