Thanks Nils and Alexander,</div>

I am still on the verge of increasing the heap size for my simulation. I have been increasing it gradually in order to find out which will work comfortably. At the moment I have increased it to 8g (8589934592 bit = 8gb) but it still goes to memory
issues. Also, I would like to kindly inquiry if it is possible to use BonnMotion to stimulate obstacle mobility in NS2 or can you kindly advice how I can simulate obstacle mobility. Thank you for your kind response.</div>

Dear Noah,<br>
<br>
I'm not too familiar with the RPGM model (implementation), so I can't<br>
give you any advice regarding your specific model parameters, but:<br>
<br>
The -i parameter increases the overall simulation time to the sum of the<br>
values passed with parameters -i and -d. For the results, the initial i<br>
seconds are cut from the created movement file. This might be needed to<br>
remove "weird" effects of an initial transient simulation state, which<br>
might occur before a steady state is reached, from your results. Whether<br>
this is necessary depends on several factors (e.g., model, parameters,<br>
scenario, ...).<br>
<br>
I gave your command line a try on my Ubuntu based system with a slightly<br>
older Java version, seems to work fine (results attached):<br>
:/software/bonnmotion-3.0.1/bin$ ./bm -f battleFiled_60_6 RPGM -d 1000<br>
-i 0.0 -n 60 -x 1000 -y 1000 -a 5.0 -h 6.0 -l 0.0 -p 2.0 -c 0.0<br>

Increasing the number of nodes, I ran into memory issues around 6e5<br>
nodes, but this was clearly stated in the error message I received and<br>
potentially could be fixed by increasing the heap size.<br>
<br>
Best regards,<br>

> I am using Bonnmotion to create RPGM mobility scnarios for 10, 20, 30, 40, 50 nodes individually, using fixed speeds of 6, 12, 32ms (-h 6 -l 0.0), I intensionally did not give any seconds to skip(is that alright?). I have a scenario duration time of 1000.<br>
