Media-Aware Retransmission Timeout Estimation

Developing error-control and error-resiliency methods for transmitting delay-sensitive media content over the best-effort networks poses several challenges. Due to the lack of QoS guarantees in the conventional Internet as well as in emerging wireless networks, these methods must continuously monitor the characteristics of the underlying network and try to infer the incipient network conditions so that they can take the necessary actions on time. This is utmost important for enhancing the end-user quality, particularly in low-delay multimedia applications. In this study, we tackle this problem from an error-control method perspective and develop an innovative framework that optimizes the retransmission decisions based on the urgency and importance of the media packets.
