Abstract: A relay directional molecular communication method based on multiple attractants is applied in a field of molecular communication to address the inefficiency of existing technologies. The method for relay nodes is used by fixing three types of attractants, and the relay nodes only release one of the three types of attractants. By using relative priority between two attractants, nanomachines can quickly find a target. Compared with existing multi-attractant multi-relay algorithms, the method does not require many types of attractant resources due to the three types of attractants, saves a variety of the attractant resources, and still achieves an effect greater than three hop relays. It is realized that when a number of the relay nodes is certain, not only the type of attractants used can be reduced, but also the efficiency of finding the target can be maintained.
