Molecular Communication Channel Modeling and Error Probability Analysis

In this review, we delve into the realm of molecular communication, where information is conveyed through the movement of molecules in a specific environment. We explore various models used to represent receivers and transmitters in these interactions, demystifying complex concepts by using everyday language and analogies.
Receivers: The most common model is the passive receiver, which allows molecules to freely diffuse within its space without any movement being affected. This simple model is often used as a starting point for analyzing other aspects of molecular communication systems, such as the environment boundary.
Transmitters: The most common transmitter model represents it as an ideal point source that releases molecules instantaneously, disregarding physical geometry and realistic release mechanisms. However, more advanced models have been proposed, including the pulse-shaped release from a point source transmitter, which allows for multiple molecules to be released during the pulse, and the box-like transmitter with a surface outlet for controlling molecular release.
In summary, this review sheds light on the complex concepts of molecular communication by breaking them down into digestible chunks using relatable analogies and language. By understanding the different models used to represent receivers and transmitters, readers can gain a deeper appreciation for the intricacies of this fascinating field.
