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.
