A Simple Distributed Algorithm Simulator for Research and Teaching. The simulator is based on WsnSimPy. It has also visualized version in it.

Install SimPy library

pip install simpy

There are three examples which are flood, flood_vis, and aodv. The flood and flood_vis examples simulate the flooding algorithm. The flood_vis is a visualized version of the flood example. The aodv simulates the AODV routing algorithm in the visualized version. Execute them via command line:

python -m flood.py

python -m flood_vis.py

python -m aodv_vis.py

Step 1: Import DawnSim.

from source import DownSim

Step 2: Create a node class that inherits DawnSim.BaseNode to simulate a single node.

class MyNode(DownSim.BaseNode):
    pass

Step 3: Override init(), run(), on_receive(pck), and finish() functions (only the necessary ones).

class MyNode(DownSim.BaseNode):
    def run():
        pck = {'var1': 'val1', 'var2', 'val2'}
        self.send(DawnSim.BROADCAST_ADDR, pck)

Step 4: Create a new DawnSim.Simulator object.

my_sim = DawnSim(duration = 100)

Step 5: Add nodes into the simulator via add_node() function.

my_sim.add_node(MyNode, pos = (50, 50), tx_range = 75)
my_sim.add_node(MyNode, pos = (50, 100), tx_range = 75)

Step 6: Call the run() to start the simulation.

my_sim.run()
