DESCRIPTION:Dr. Rohan Murty\, Harvard University - IC Faculty candidate\nA
 bstract : With wireless networks slated to become the dominant method of i
 nternet access of the future\, the radio spectrum is fast becoming a scarc
 e and expensive resource.  Despite the significant growing pressures on th
 e demand for spectrum\, there are large portions of the overall spectrum t
 hat are severely under-utilized ultimately leading to inefficient use of a
 vailable capacity. To address these problems we build opportunistic wirele
 ss networks\, which work by continually seeking and using portions of the 
 spectrum that are unused by the spectrum owners (incumbents) while ensurin
 g non-interference with the incumbents. A prominent emerging system where 
 opportunistic wireless networking can work well is in the so-called white 
 spaces. Enabled by two historic rulings (in 2008 and 2010) by the Federal 
 Communications Commission (FCC) in the United States\, white spaces are th
 ose television channels that\, in an instant in time\, are not used by the
 \nincumbents: television stations or wireless microphones.\n\nIn this talk
  I will present the challenges encountered when building the next generati
 on of wireless networks that operate opportunistically over these white sp
 aces.\, I will first present WhiteFi\, which consists of new algorithms an
 d protocols for networking over the white spaces. I will then present Sens
 eLess\, a white spaces network that obviates the need for white space devi
 ces to sense the presence of incumbents. I will present results and evalua
 tions from prototype implementations and deployments of the two systems.\n
 \n\nBio: Rohan Narayana Murty is a doctoral candidate in the Computer Scie
 nce Department at Harvard University. He received an undergraduate degree 
 in Computer Science from Cornell University in 2005. His research interest
 s span networked systems including networks\, mobile computing\, and distr
 ibuted systems. His thesis work has won the best paper at at SIGCOMM 2009\
 , the Microsoft Research Graduate Fellowship\, a Siebel Scholars Fellowshi
 p\, and a Jim Gray Seed Grant.
