DESCRIPTION:Sachin Katti\nAbstract:\nWireless is becoming the preferred mo
 de of network access. The performance of wireless networks in practice\, h
 owever\, is hampered due to the harsh characteristics of the wireless medi
 um: its shared broadcast nature\, interference\, and high error rate. Trad
 itionally\, network designers have viewed these characteristics as problem
 atic\, and tried to work around them. In this talk\, I will show how we ca
 n turn these challenges into opportunities that we exploit to significantl
 y improve performance.\n\nTo do so\, we use a simple yet fundamental shift
  in network design. We allow routers to “mix” (i.e.\, code) packets’
  content before forwarding them. We built three systems\, COPE\, ANC and M
 IXIT\, which exploit this network coding functionality via novel algorithm
 s to provide large practical gains. In this talk\, I will discuss COPE and
  ANC\; COPE exploits wireless broadcast\, while ANC exploits strategic int
 erference to improve throughput.\n\nThis work bridges and contributes to t
 wo unrelated areas: network coding and wireless mesh network design. It la
 ys down the algorithmic framework for using network coding in modern wirel
 ess networks\, by designing algorithms which work with the common case of 
 unicast flows in dynamic and unknown environments. It also provides the fi
 rst implementation\, deployment and experimental evaluation of network cod
 ing. For wireless mesh networks\, it shows how the framework of network co
 ding allows us to profitably harness the inherent wireless characteristics
 . This union ultimately allows us to deliver a several-fold increase in wi
 reless throughput.\n\nBio:\nSachin Katti is currently a postdoctoral schol
 ar at U.C. Berkeley. He received his PhD in EECS from MIT in September\, 2
 008. Before coming to MIT\, he received his B.Tech. in Electrical Engineer
 ing from the Indian Institute of Technology\, Bombay\, in 2003. His disser
 tation research focuses on redesigning wireless networks with network codi
 ng as the central unifying design paradigm. The dissertation won the Georg
 e Sprowls Award for Best Doctoral Dissertation in EECS at MIT and has been
  nominated for the ACM Doctoral Dissertation Award. His work on network co
 ding was also awarded a MIT Deshpande Center Grant. His research interests
  are in networks\, wireless communications\, applied coding theory and sec
 urity.\nKatti's home page
