Area of Science:

• Biomedical Engineering
• Computational Biology
• Nanotechnology

Background:

• Molecular communication systems, vital for nanomedicine like targeted drug delivery, face scalability challenges due to massive interacting entities.
• Existing simulation tools struggle with the complexity and time demands of analyzing these systems.

Purpose of the Study:

• To develop a simplified yet reliable receiver model for diffusion-based molecular communication systems.
• To address the computational time constraints in analyzing molecular communication systems.

Main Methods:

• Proposed an equivalent Markovian queuing model to simulate the aggregate behavior of numerous surface receptors.
• Accounted for receptor-mediated molecule absorption and non-instantaneous binding processes.

Main Results:

• The Markov queuing model accurately reproduced results from particle-based simulations involving thousands of receptors.
• The proposed model achieved simulation results an order of magnitude faster than traditional particle-based methods.

Conclusions:

• The developed Markov queuing model offers a computationally efficient and reliable approach for simulating molecular communication systems.
• This model can serve as a foundation for simulating larger and more complex molecular communication systems, advancing nanomedicine research.
