Colloquium - Heusse

ECCR 150

Layer 2 (and Above) Performance Enhancements in 802.11 Wireless LANs
Université Joseph Fourier, Grenoble

This talk covers recent developments in the field of wireless networks, focusing on improving user experience in the infrastructure mode. This requires to take into account the specific role of the access point that acts as a bridge with the wired part of the network, but also runs the same access method as other stations. The access point would require more transmission attempt probability than wireless stations for correct operation at the transport layer, to obviate the unfairness between uploads and downloads that we observe in current WLANs. We will detail two approaches to this problem, one at the link layer, by giving the access point the necessary priority; the other one at the network layer, by using an adequate queueing policy.

Martin Heusse is an Assistant Professor at the Joseph Fourier University in Grenoble, and is a member of the LIG laboratory. He graduated from Telecom Bretagne engineering school in 1996 and received his PhD in 2001. His main research interests are the design and evaluation of access methods in wireless LANs and sensor networks.

The Department holds colloquia throughout the Fall and Spring semesters. These colloquia, open to the public, are typically held on Thursday afternoons, but sometimes occur at other times as well. If you would like to receive email notification of upcoming colloquia, subscribe to our Colloquia Mailing List. If you would like to schedule a colloquium, see Colloquium Scheduling.

Sign language interpreters are available upon request. Please contact Stephanie Morris at least five days prior to the colloquium.
