A few questions in my mind
1: How does a reliable link-layer protocol that is TCP-aware improve performance in lossy wireless networks, and is it possible to achieve good performance without breaking the end-to-end connection at the base station?
2: Are there any limitations to the use of reliable link-layer protocols in improving TCP performance in wireless networks?

Thank you for your comments on our research article "Wireless Network: Performance Analysis of TCP."
To answer your questions:
A reliable link-layer protocol that is TCP-aware improves performance in lossy wireless networks by providing local reliability. By shielding the TCP sender from duplicate acknowledgments caused by wireless losses, it allows TCP to perform well without invoking congestion control and avoidance algorithms, resulting in improved throughput by 10-30%. It is possible to achieve good performance without breaking the end-to-end connection at the base station by using such a protocol.
There may be some limitations to the use of reliable link-layer protocols in improving TCP performance in wireless networks, such as increased overhead and complexity, which can negatively impact performance in some cases. However, the benefits of using a reliable link-layer protocol generally outweigh the limitations in lossy wireless networks.
We hope this helps answer your questions and provides a better understanding of the research findings. Thank you for your interest.
