SUMMARY:Managing Enterprise Wireless LANs Using DAIR (Networking Seminar)
  Ranveer Chandra\, Microsoft Research-Redmond
CREATED:20070904T130000Z
DESCRIPTION:Wireless networks are fundamentally more difficult to manage 
 than wired networks. The wireless medium is more unpredictable\, and the
  performance on the network varies significantly with location. In this 
 talk\, I will first motivate the need for a dense deployment of sensors 
 for managing enterprise Wireless LANs (WLANs) and then present a new sys
 tem\, called DAIR (for Dense Array of Inexpensive Radios)\, that achieve
 s this requirement. DAIR is based on two observations. First\, in most e
 nterprise environments\, one finds plenty of desktop machines with good 
 wired connectivity\, and spare CPU and disk resources. Second\, inexpens
 ive USB-based wireless adapters are commonly available. By attaching the
 se adapters to desktop machines\, and dedicating the adapters to the tas
 k of monitoring the wireless network\, we create a low cost management i
 nfrastructure.We have built and deployed three applications on top of th
 e DAIR framework. First\, we use DAIR to detect security breaches\, such
  as rogue APs\, in the enterprise WLAN. Second\, DAIR helps us locate Wi
 -Fi clients and identify regions of poor or no WLAN coverage. Finally\, 
 we are exploring a new architecture where we can turn every desktop into
  an Access Point to improve the capacity of the WLAN. I will present the
 se three applications and some of the other work I am currently doing. T
 he DAIR project is joint work with Jitu Padhye\, Alec Wolman\, Brian Zil
 l\, Rohan Murty and Victor Bahl.Bio: >Ranveer Chandra is a Researcher in
  the Networking Research Group at Microsoft Research in Redmond\, WA. He
  completed his PhD in Computer Science from Cornell University in 2005. 
 As part of his thesis he developed VirtualWiFi\, which is a virtualizati
 on architecture for wireless cards. The software has been downloaded mor
 e than 70\,000 times\, and was covered by various sites\, including CNET
 \, eWeek and Slashdot. More recently he has been working on cognitive ra
 dios and various aspects of wired and wireless network management.
