Apologize for the empty mail before. The question I wanted to ask you with regards to running TOSSIM-2.x with arpproximately 500 nodes (more is even better). My simulation runs fine with around 100 nodes but anything beyond that the simulation segfaults.
In order to stress TOSSIM-2.x and remove any ambiguities, I tried running the blink application for around 130 nodes and after booting up the simulation simply hanged.
The application I am trying to simulate is a random walk. It works fine for 50 nodes. But apart from the nature of the application what was bothering me was the fact that nodes are not able to boot up itself.
The loop I am using to boot up the motes is as below, I hope I am not making a mistake with the booting up process:
for i in range(0, NUM_SIM_NODES):
node = sim_obj.getNode(i);
node.bootAtTime(sim_obj.time() + i*10000);
while True:
sim_obj.runNextEvent();
if node.isOn() :
print "Commpleted booting node "+str(i)
break
#create links between nodes
sim_radio.setNoise(i, -105, 3.0);
for j in range (0,NUM_SIM_NODES):
if (j != i ):
sim_radio.add(i, j, -50.0);
Wanted to know your views on this.
regards,
Avinash
