void4 / netsim

Simulates a simplified meshnet environment

NetSim

should probably be called MeshSim. Works with Stackless Python.

python3 main.py

Simulates p2p nodes in a 2d wireless environment. Peers may receive flag messages that they must transmit to other specific nodes. Collaboration is necessary. New Peers should subclass Peer and only specify two functions:

• setup: Called once at node creation, should be used to setup self.state
• update: Called as long as the node is alive, can send() packets and read from self.recvarr

All state should reside in the self.state dictionary so it can be easily analysed.

Output example:

ITER:39 FPS:6 Sent:269389 Recv:449557 Backlog:178771 Flags:500 Cleared:80
