vlcsim

VLCsim - Visible Light Communication Network Simulator.

A discrete-event simulation framework for modeling and analyzing Visible Light Communication (VLC) networks with Time Division Multiplexing (TDM) resource allocation.

Modules:

scene: Physical environment modeling including room dimensions, LED access points,

RF fallback systems, and mobile receivers with realistic VLC channel propagation.

controller: Resource allocation and connection management system handling TDM frame

slice assignment, connection state machine, and custom allocation algorithms.

simulator: Event-driven simulation engine implementing discrete-event system (DES)

for network dynamics, traffic generation, and performance metrics collection.

Example

Basic simulation setup:

from vlcsim import Scenario, Simulator

# Create scenario with room and devices
scenario = Scenario(length=5, width=5, height=3)
scenario.add_VLed(x=2.5, y=2.5, z=3)

# Run simulation
sim = Simulator(scenario)
sim.run()
print(f"Blocking Probability: {sim.get_Blocking_Probability()}")
