Is aodv simulation normal or not ?

[Michael W.S. Yee]

Hi everyone,
I use the testing code "examples/routing/manet-routing-compare.cc" to test aodv routing performance, in the simulation, set up 10 sinks, 5Mbps for each on/off Application, Packet size is 5000 Bytes, and the simulation lasts 200 seconds, 0~50 seconds is going to setup the network topology, 51~200 seconds doing the simulation.
When network scale is 10 nodes, the throughput is a normal value from 51s~200s, but with 50 nodes, the performance gets so poor that the throughput is close to 0 from 180s~200s. Is this means a serious congestion happened in the network ?

What's the ns-3 version?

ns-3.12 and ns-3-dev get the same results.

I can see a flood of RREQ and RREP around 178 second region. This really should not have happened for stationary nodes.

i believe this a bug. Can you file it on, https://www.nsnam.org/bugzilla/

Thanks for your testing, I'll file it as soon.

Hello,

In this algorithm there is mobility? I do not understand how it works,
can you explain, is that I am new to the NS3!
