Also the figure from the paper shows a round trip time of around 5ms so you should set your link delay accordingly to get this RTT (not 20ms as suggested earlier).<br>

<div>and as you can see there are some problems:<br>
</div>
<div>(1) the values on the y-axis is much higher than in the paper, I figured out that It's caused by the delay, I set the delay for every link to 20ms so the values are around 80ms but when I set the delay to 0ms the values are around 10ms but the
swing of values become more and values are not united like when the delay is 20ms<br>
</div>
</span><div><span class="">(2) as you can see when node4 fails we have some values that shows something happened:<br>

<div>but this values doesn't exist in my figure.<br>
</div>
<div>(3) the density of red points in my figure isn't the same in all aspects.<br>
