Hybrid Adaptive Loss Recovery and Enhanced Retransmission Technique for VoIP

摘要

VoIP is an emerging technology, where the voice information is transmitted through the Internet. This technology is very useful but at the same time very challenging due to its susceptibility to various network variations. The VoIP packet transmission can get degraded easily and thus resulting in the packet loss, which in turn degrades network performance. In this paper, we propose to develop a hybrid adaptive loss recovery and enhanced retransmission technique for VoIP. In this technique, the sender and the receiver separately work on error correction of the damaged packets to enhance the network performance. The sender employs the FEC codes to retrieve the damaged packets. The receiver deploys the Packet Loss Concealment (PLC) technique and the FD retransmission technique dynamically according to the network requirements, to enhance the network performance.
