Retransmission-based error recovery is the simplest technique to minimize the overall packet loss ratio in order to increase the quality of the applications. Multimedia applications are becoming increasingly popular in IP networks, while in mobile environment the limited bandwidth and the higher error rate arise in spite of its popularity. Retransmission can be also used for loss recovery in media applications, but the number of retransmissions is limited by the playout buffer and the recent network delay. In this paper we present a source controlled adaptive multiple retransmission scheme for multimedia streaming. Due to source controlling the receiver do not need to send additional retransmission request messages. The other advantage of transmitter controlled decision algorithm is that the necessary RTT information is available at the source due to DCCP transport protocol. Therefore no additional network measurements and probe messages are needed. With the knowledge of the actual network delay and the playout buffer delay, we are able to determine the number of retransmission attempts without late delivery of packets.
