Description

technical field [0001] The invention relates to biotechnology, nanotechnology and communication technology, and is an energy efficiency optimization method for a two-hop mobile molecular communication system. Background technique [0002] In mobile molecular communication, nanomachines are in a moving state, which is more common in many practical applications (such as drug delivery in the human body, health monitoring, target detection, etc.). Therefore, mobile molecular communication is the most important and practical way of molecular communication in nano-networks. Different from the molecular communication system of static diffusion, in the mobile molecular communication model, both the sending nanomachine and the receiving nanomachine are in a moving state, and their positions change randomly. Therefore, in the mobile molecular communication system, the mobility of nanomachines causes the distance between nanomachines to change with time, and the channel impulse respon...
