Use different handoff policies to evaluate the performance.

Handoff Simulator

Introduction

• A simple simulator used four different handoff policies.
  • Best policy:

  New Power > Old Power
  

  • Threshold policy: (T = -110 dBm)

  New Power > Old Power && Old Power < T
  

  • Entropy policy: (E = +5 dBm)

  New Power > Old Power + E
  

  • Self-defined policy: (multiplier = 0.9, Minimum Power = -125 dBm)

  New Power > Old Power * multiplier && New Power > Minimum Power
  

• Each point represents a car. Use Poisson Distribution to assume that there are 2 cars/min entering to this zone. The simulation time is for one day(=86400 seconds).
• When a car meet the intersection, there are different possibilities to different directions.
  • Straight:
  • Right:
  • Left:

Result

• To watch the simulation for 86400 seconds, run:

python simulator.py

• To plot policy comparison figure and print the result, run:

python main.py

It may cost 10~20 minutes to plot the figure and print the result.
