Summary
Recall the general model for a molecular communication system, presented in Figure 4.1 (Chapter 4), which is composed of sender and receiver bio-nanomachines, information molecules, and other molecules (or bio-nanomachines) that support communication between the sender and receiver bio-nanomachines such as interface, guide, transport, and addressing molecules. These components of molecular communication systems use biological or molecular machinery to implement specific functionalities:
• Sender and receiver bio-nanomachines encode and decode messages. At the sender bio-nanomachine, a molecular encoder transforms a message, such as the internal state of the bio-nanomachine or the external condition of the bio-nanomachine, into an appropriate signal. At the receiver bio-nanomachine, a molecular decoder transforms a signal into a useful state or action of the receiver bio-nanomachine.
• Information molecules function as signals to carry a message. An information molecule may occupy distinct states. If the encoder can set the state and the decoder can detect the state, the state can carry a message.
• Interface molecules encapsulate the signal and protect from noise in the environment during propagation. The signal can be passed out of the transmitting bio-nanomachine to an interface molecule during sending, and the signal can be passed from the interface molecule into the receiving bio-nanomachine during receiving.
• Guide or transport molecules can direct the signal from the transmitting bionanomachine to the receiving bio-nanomachine, in a way that is different from diffusion in free space.
