An adaptive sender-based VoIP loss-recovery technique

Many techniques were proposed for improving quality of service (QoS) in the face of packet loss in Voice over Internet Protocol (VoIP) networks. The Sender-Based loss recovery techniques is commonly used to improve QoS when packet loss occurs by retransmitting data or by transmitting additional data. This research introduces a newly developed adaptive sender-based loss recovery technique. A simulation study is made to evaluate the techniques performance and its impact on QoS for calls delivered through the network. The performance results showed that the proposed adaptive technique achieved a lower average delay, delay jitter and higher throughput when compared to traditional Redundant Technique.
