In this letter, we analyze the SIP transfer delay over multi-rate wireless networks where different transmission modes based on adaptive modulation code are supported. We consider a Nakagami m fading channel at the physical layer and automatic repeat request at the data link layer. Extensive simulation results are given to validate the analytical results and to demonstrate the effects of message sizes and channel conditions.
