In this paper two different rateless transmissionschemes are developed. In the proposed scheme, relay node candecode and forward the message to the destination if they areable to decode it, or amplify and forward the message to thedestination. Based on the analysis and simulation resultsprovided in this paper, the proposed method has bettertransmission time than the scheme which only the relay nodesthat have already decoded the message participate in the secondphase. Due to the simplicity of the amplify and forwardtransmission, adding this feature to the network can result inbetter performance without any additional complexity.
