To analyze the performance of underwater acoustic wireless sensor networks ( UAWSNs) in the presence of interference. The related interference factors affecting network performance were introduced. The acoustic com-munication interference model in physical level of UAWSNs was designed. Based on frequency dependent path loss and Ricean fading the channel model was built. The relationship among the coverage, end-to-end frame error prob-ability, power and bandwidth requirements to be used as the network connected logo was researched. The UAWSNs performance under the interference between nodes was analyzed. The feasibility of the design model was validated by simulation experiments. The experimental results show that the priority transmission power and nodes density can ensure normal operation of the network, and improve the reliability of the network.
