Abstract—Losses due to network problems can result in jitter with streaming technologies, voice over IP, online gaming and videoconferencing. It will affect all other network applications to a certain degree. The uncorrected data loss leads to packet loss at the decoder. This packet loss is uncorrectable producing video and audio issues. In this paper we propose an agent based loss recovery technique for multimedia flows in IP networks. In our work we use relay nodes between ingress and egress nodes and develop a Hybrid FEC/MDC coding scheme in order to perform effective loss recovery while transmitting multimedia data between source and destination. By simulation results, we show that our proposed approach attains high throughput with reduced packet loss when compared with the existing technique.
Index Terms—IP Networks, forward error control (FEC), multiple description coding (MDC), multimedia, loss recovery technique.
