Good question! This is just something I want to do. But it didn't just randomly pop up in my mind. I'm a student, and I have taken the course about wireless network last semester. I got a project assignment to write a little simulation in Python, and here is the link https://github.com/chonyy/handoff-simulator.

I found it interesting while I'm building the little simulation in Python. And i think "What if I can visualize this simulation? It would be really cool!" So, I just built it during my holiday :)

Please do be aware there are difference between the visualizer and the simulator. The parameters in the simulator project is closer to our real world, so i have tuned some of it in this visualizer to make it more pleasing to the eyes.
