Results of simulation based experiments demonstrate considerable performance improvement with the proposed modifications over the conventional TCP, when a wireless sender is experiencing frequent link ...
The proposed modifications which depend on interaction between two layers (i) reduce the idle time before transmission at TCP by preventing timeout occurrences and (ii) decouple the congestion control ...
This results into false Round Trip Time (RTT) estimation leading to an increased RTO interval. A longer RTO interval subsequently prevents TCP from regaining the available network bandwidth, sooner. ...

Furthermore, our results also substantiate the fact that the media-aware RTO estimator outperforms all other RTO estimators in terms of video quality. ...
In the media-aware mode, on the other hand, the timeout estimates are jointly optimized based on the importance and urgency of the video packets such that the rendering quality is maximized under the given ...
One important issue in RTO estimation is the rapid convergence of the timeout estimates. Based on our simulations, we found that RTO E−TCP required at least 15-20 samples to produce good estimates. ...
