# BLE-mesh SIM
This is a simulation of a BLE-mesh network. It uses the [vis-network](https://visjs.github.io/vis-network/docs/network/) library to visualize the network.
This is a simulation of a BLE-mesh network. It uses the [vis-network](https://visjs.github.io/vis-network/docs/network/) library to visualize the network itself, and a heavily modified version of [vis-network-moving-nodes-on-edges](https://github.com/delcourtfl/vis-network-moving-nodes-on-edges) to visualize the movement of packets through the network.
Currently this is not an accurate simulation of my BLE-mesh project. The goal is to finalize this simulation so that I can use it to test things like connection heuristics and ensure that network formation is optimal. I might also use this to test building routing algorithms to see how they perform under different network topologies.
At this point the simulation is almost perfectly accurate, with the exception of packet origin tracking, which is being worked on.
You can:
- Add nodes to the network
- Topology will be updated automatically in the same way as the real network
- Configure a wide variety of simulation settings to see how they affect the network
- Create random networks with massive node counts (200+)!
- Send flood packets through the network and see how they travel through the network
When sending packets, the colors of each node will change to reflect the TTL of the packet. The more green a node is, the closer it was to the origin of the packet, the more red a node is, the further it is from the origin. Nodes that were unable to receive the packet will turn white (this is often due to low TTL on large networks).
I have also found that this simulation can vary wildly in performance depending on the machine it's running on. Make sure your browser supports GPU acceleration, or else this will run very poorly with large networks.
You should be able to run this simulation by opening the `index.html` file in your browser, there's no fancy stack or anything, just pure HTML, CSS, and JavaScript.
