Abstract Sensor deployment is related directly to the cost and performance of underwater sensor networks. Considering great cooperative capability of sensor nodes, this paper presents a deployment strategy based on detection fusion. Neyman-Pearson criterion is adopted to fuse the detection information from all sensor nodes in one unit grid, which realizes highly efficient coverage for square and triangle unit grid. The grid plot methods of detection field are presented respectively for two types of unit grid. The number of sensor nodes to monitor the detection field and their locations are determined consequently. The effectiveness of proposed deployment strategy is verified by simulation experiments. The results indicate that sensor node redundancy is decreased in contrast to deployment strategy without detection fusion. With fixed quantity of sensor nodes, the new deployment strategy offers larger coverage area with the desired detection accuracy.
