Channel Modeling for Multi-Receiver Molecular Communication System by Impulsive Force in Internet of Nano Things

Area of Science:

• Electrical Engineering
• Computer Science
• Nanotechnology

Background:

• Molecular communication (MC) systems in fluid environments face challenges due to fluid resistance.
• Modeling MC in single-input multiple-output (SIMO) systems is complex due to fluid effects and inter-receiver interference.

Purpose of the Study:

• To incorporate fluid resistance into a 3D SIMO model for MC systems.
• To analyze the impact of receiver angles (azimuth and polar) on molecular reception.
• To investigate inter-receiver interference patterns and derive a mathematical expression for received molecules.

Main Methods:

• Developed a three-dimensional SIMO model incorporating fluid resistance.
• Analyzed the influence of receiver angles and inter-receiver distances on molecular transmission.
• Derived mathematical expressions for the number of received molecules.

Main Results:

• Reception efficiency is maximized at specific polar (90°) and azimuth (0°) angles.
• Increasing distance between receivers and transmitters initially increases then decreases received molecules, showing nonlinear interference.
• Spatial arrangement, receiver count, and molecular velocity significantly affect performance.

Conclusions:

• The proposed model accurately predicts molecular reception in fluidic IoNT environments.
• Understanding angular and distance-based interference is crucial for optimizing MC system design.
• Receiver and transmitter positioning are key factors for efficient molecular communication.
