Reliable transport protocols like TCP have been adapted to work well for traditional wireline networks where packet losses occur mostly due to congestion. The implicit assumption in these networks is that the links are lossless, and hence they do not cause significant amounts of packet corruption. TCP responds to packet losses by invoking some congestion control and avoidance techniques. However, such an assumption is not valid for wireless networks where packets may also be lost due to channel noise. In this report we suggest modifications to TCP to improve end-to-end delay and latency characteristics in wireless networks, while maintaining end-to-end semantics. Through simulations we compare the performance of unmodified TCP and compare its performance for wireless networks to TCP extended with our modifications.
