In this paper, high reliable broadcasting protocol in WLAN using retransmission is proposed. Broadcast in conventional WLAN has advantage of high efficient use of wireless resource, but has disadvantage of low reliability and data rate. Broadcasting frame includes the sequence indicating which nodes send ACK frame first. If some nodes fail to receive the frame, the node which success to receive the frame retransmits the frame with broadcasting. By these broadcasting with relay retransmission algorithm, the probability of transmission increase when the channel is better between the nodes.
