分子通信是在纳米和微观范围内生物纳米机器之间通信的新范式。由于生物纳米机器（或者简而言之）太小且简单，无法通过传统的通信机制进行通信（例如，通过发送和接收无线电或红外信号），分子通信为纳米机器（即发送者）提供了一种机制通过传播分子（即信息分子）代表纳米机械（即接收器）的信息。本文介绍了体外分子通信系统的设计，并评估了各种方法，以最大程度地提高到达接收器的信息分子的可能性以及到达接收器的信息速率。本文考虑的方法包括传播信息分子（沿蛋白质丝的扩散或定向转运），去除过多的信息分子（自然衰变或接收器去除过多的信息分子），以及编码和解码方法（冗余信息分子以表示信息，以表示信息以及信息以及信息以及信息和信息分子，以及信息以及信息分子以及信息和解码方法解码信息）。考虑了两种类型的分子通信系统：一个单播系统，其中发件人与单个接收器和广播系统进行通信，其中发件人与多个接收器进行通信。通过在两种类型的分子通信系统上探索各种方法之间的权衡，本文确定了有希望的方法，并显示了体外分子通信系统的可行性。
Molecular communication is a new paradigm for communication between biological nanomachines over a nano-and microscale range. As biological nanomachines (or nanomachines in short) are too small and simple to communicate through traditional communication mechanisms (e.g., through sending and receiving of radio or infrared signals), molecular communication provides a mechanism for a nanomachine (i.e., a sender) to communicate information by propagating molecules (i.e., information molecules) that represent the information to a nanomachine (i.e., a receiver). This paper describes the design of an in vitro molecular communication system and evaluates various approaches to maximize the probability of information molecules reaching a receiver(s) and the rate of information reaching the receiver(s). The approaches considered in this paper include propagating information molecules (diffusion or directional transport along protein filaments), removing excessive information molecules (natural decay or receiver removal of excessive information molecules), and encoding and decoding approaches (redundant information molecules to represent information and to decode information). Two types of molecular communication systems are considered: a unicast system in which a sender communicates with a single receiver and a broadcast system in which a sender communicates with multiple receivers. Through exploring tradeoffs among the various approaches on the two types of molecular communication systems, this paper identifies promising approaches and shows the feasibility of an in vitro molecular communication system.
