Enhancement of adaptive FEC mechanism for video transmission over 802.11 WLANS

Forward Error Correction (FEC) techniques have been adopted with Automatic Repeat reQuest (ARQ) to overcome packet losses and avoid network congestion in various wireless network conditions. The number of FEC packets need to be generated adaptively because usually wireless network has varying networ...
