Multiple description coding forMJPEG2000 overcongested 802.1 lewirelessLANs

Theefficient transmission ofvideocontent over wireless communication networks isachallenging goal, especially whenconsidering multiple mobile usersequipped withenergy- constrained handheld devices andsharing thesamechannel resources. Inthepresent work,considering thescenario of thereal-time delivery ofmultiple MJPEG2000videostreams overa QoS-enabled 802.11e wireless LAN,we investigate the performance ofmultiple description coding andcompareitwith different video transmission techniques. We analyze ifandwhen dataredundancy oftheinformation source canimprove theend- to-end perceived quality inthis realistic multi-user scenario.
