Colloquium - Heusse

Layer 2 (and Above) Performance Enhancements in 802.11 Wireless LANs
Université Joseph Fourier, Grenoble
5/20/2008
3:30pm-4:30pm

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.
