Performance study of a Random P-Persistence sender-based VOIP loss-recovery technique

Voice over Internet Protocol (VOIP) is a technology that transports voice data packets across packet-switched networks using the Internet Protocol (IP). Losing packets in the network is inevitable, and losing voice packets degrades audio quality. The Sender-Based loss-recovery techniques can be used to mitigate the undesired effects of packet loss in VOIP system. In this Paper we introduce a newly developed Random P-Persistence sender-based loss recovery technique for VOIP network. A simulation study is made to evaluate the techniques performance and its impact on QOS for calls delivered through the VOIP network. The performance results showed that the proposed Random technique achieved a lower average delay and delay jitter when compared to traditional sender-based redundant technique.
