[Tinyos-help] The largest number of motes TOSSIM can simulate

[Chris Yao]

Hi,
   
  I am wondering the largest number of motes TOSSIM can simulate.
   
  I am using XubunTOS. I write a Driver.c simulation program. It works fine 
with 4 nodes.
   
  When I use 5000 nodes, I have the following code segment in Driver.c
   
  ====
  #define Num_of_Nodes 5000
  ...
    for (i = 1; i <= Num_of_Nodes; i ++)
  {
   t->getNode(i)->addNoiseTraceReading((int)temp_noise);
    }
   
  =====
   
  when I use gdb to debug, the above code gives the following error:
   
  ====
  Program received signal SIGSEGV, Segmentation fault.
0x0804e752 in sim_noise_trace_add (node_id=65535, noiseVal=-98 '\236')
    at /opt/tinyos-2.x/tos/lib/tossim/sim_noise.c:93
93        noiseData[node_id].noiseTrace[noiseData[node_id].noiseTraceIndex] = 
noiseVal;
  ===
   
  Can anyone give me some advice?
   
  Thanks,
   
  Chris
