The invention discloses a communication method in a wireless Ad hoc network. The method comprises the following steps: transmitting a broadcast message to the network by each node circularly used as the broadcast source node in the network, wherein the message the broadcast ending time of the broadcast source node in the data sharing period, and each node calculates the broadcast time when used as the broadcast source node according to the broadcast message; and re-transmitting the broadcast message after the node receives the broadcast message to achieve broadcast communication between the nodes in the network, wherein a distance-based waiting time random estimation delay selection algorithm is adopted by the network layer in the re-transmission process to achieve back-off, a combined network layer is adopted by the medium access control layer to achieve unified back-off, and the medium access control layer is CSMA/CA mechanism based on IEEE802.11 protocol. The method solves the problems of broadcast route m
