摘要：Video transmission over the wireless network faces many challenges. The most critical challenge isrelated to packet loss. To overcome the problem of packet loss, Forward Error Correction is used by adding extrapackets known as redundant packet or parity packet. Currently, FEC mechanisms have been adopted together withAutomatic Repeat request (ARQ) mechanism to overcome packet losses and avoid network congestion in variouswireless network conditions. In the current work An Enhanced Random Early Detection Forward Error Correction(ERED-FEC) mechanism is implemented to improve the quality of video transmissions over Wireless Local AreaNetworks (WLANs). The aim is to improve recovery performance on the current Adaptive FEC mechanism byinjecting FEC packets dynamically based on varying wireless network conditions. Based on the findings, the optimalamount of FEC generated by Enface mechanism can recover high packet loss and produce good video quality
