Most wireless networks incline to include FEC code (Forward error correction) to recover the corrupted packets without retransmission. The sequential packets transmitted over wireless channel are likely to be infected with various errors like noise or deep fading. In this paper, therefore, a frame-level FEC is added across packets at the application layer to define two analytical packet loss models. At the network layer level, Gilbert Elliot Model (GEM) and Extended Gilbert Model (EGM) are…

An Adaptive Fuzzy based FEC Algorithm for Robust Video Transmission over Wireless Networks

An adaptive, Fuzzy based FEC algorithm to provide a robust video quality metric for multimedia transmission over wireless networks has been proposed to optimize the redundancy of the generated code words from a Reed-Solomon encoder and to save the bandwidth of the network channel.

Neural Network-based Video Quality via Adaptive FEC in Wireless Environment

This proposal strives to address QoS of video streaming for the cellular clients in Universal Mobile Telecommunication System (UMTS) through adaptive FEC based on ANN, and shows that a video quality can be adaptable to the tuned optimal FEC codes from ANN via the packet loss probability of the wireless feedback environment.

A Study of MPEG Video Transmission in Lossy Wireless Networks

An analytical model is used to derive an application-level evaluation metric, the Decodable Frame Rate (Q), which is more sufficient for the end users to evaluate the video quality than other network-level metrics, such as packet delay, loss rate, or delay jitter.
