Abstract :
Allowable delays in multimedia transmission are an important factor for media synchronization. Automatic repeat request (ARQ) is a very popular protocol for error correction. However, long propagation delays and high packet error-rates make long total packet delays. If the received packet has a longer delay than the allowable delay then it will be lost. This loss reduces the quality of the multimedia applications. To solve this problem, an adaptive protocol relay capability is proposed. Having this capability allows the protocol to be adaptively terminated at the relay nodes. However, the error correction between the protocol relay nodes still requires a small delay. We analyze the relationship between the protocol relay capability and the total loss of media transmissions with allowable delay. Also, the criteria for this adaptive protocol relay is described
