Optimization of repair process in reliable multicast transport protocol over wireless channel
Han Li · Computer Engineering and Applications Journal · 2012
For wireless channels are inherently lossy,it is challengeable to maintain the Quality of Service(QOS)for live streaming. NORM(NACK Oriented Reliable Multicast)repair process uses time slot as the base mechanism,which results in long repair cycle. The feedback round algorithm is applied to optimize the repair process.This algorithm allows receiver to send NACK in rounds and sender response repair requests immediately.So that the delay for waiting response from sender is distributed to each round.Experimen- tal results show that the protocol gets much higher performance than NORM in live streaming on wireless channel.
