Paper Review: Congestion Control in Wireless Environments
Reviewer: Mark Meras (mm446)
This paper by Balakrishnan et al. discusses different techniques of
improving the performance of TCP over wireless links. This is a review of
current work and experiments on it.
- There are three main categories of techniques to improve end-to-end
performance of TCP over wireless links: end-to-end, link-layer, and
- A link-layer solution aware of TCP (LL-TCP-AWARE) gives a 10-30%
improvement over non-aware LL solutions.
- The split-connection solution shields the user from losses, but is
shown to not be required for good performance.
- End-to-end schemes, such as the explicit loss notification scheme,
Critique of Contribution
This work is a good analysis of several options currently available
for improving wireless performance. The paper will become more and more
important as wireless links become ubiquitous. As the author argues,
end-to-end solutions for the wireless link problem will likely be a
growing area of research.
