Analysis of TCP Latency Over Wireless Links Supporting FEC/ARQ-SR for Error Recovery
Overview The study discussed in this paper is the performance of TCP over a wireless link implementing hybrid FEC/ARQ-SR at the link layer. The study is done by simulating a large number of TCP transfers over a wireless link showing Bernoulli errors. One is motivated by how to tune link-level error recovery, e.g. amount of FEC, persistency of ARQ, so as to minimize the latency of TCP. It provides results for different physical characteristics of the wireless link (delay, error rate), different traffic loads and different file sizes. The main finding is that the latency of TCP always improves with the persistency of ARQ, except for some extreme cases where the delay is large, files are small, and the loss rate is low.
