Abstract :
This article introduces a new voice packing scheme to transfer voice samples over the Internet. This method aims to reduce the voice quality degradation caused by lost packets as far as possible. Regenerating lost voice packets in active nodes in the network, introduces more received voice quality at the receiver side compared with the other methods. This scheme is simulated using an unreliable network with an active node, and it shows more voice quality than the other schemes even if the network loses 50 percent of packets.
