[SOLVED] Does ns2 has capability to implement store-carry-forward mechanism? If it has how to do that?

Does ns2 has capability to implement store-carry-forward mechanism? If it has how to do that?

I don't know ns 2 has capability to do this but I want to implement store-carry-forward mechanism in ns 2. However, I don't know where to start. Also I don't know what its steps. What protocols this mechanism uses? Is there anybody who can help me?

Solution

ns2 + DTN

If you have other ns2 builds / installs : Rename the executable´s ns to a new name → ns-orig, 'ns-app-name', etc. And remove any ns2 *PATH text from .bashrc .

Build ns2 + DTN

tar xvf ns-allinone-2.35_gcc5.tar.gz

https://drive.google.com/file/d/0B7S255p3kFXNVVlxR0ZNRGVORjQ/view?usp=sharing

cd ns-allinone-2.35/
zcat dtn_ns235.patch.gz | patch -p0
./install
cd ns-2.35/
sudo make install

Simulation : Copy an example (from ns2dtn_campaign/) to ns-allinone-2.35/, and run ./simulate_dtn.sh. The location is important as this path is used : ../ns-allinone-2.35/dei80211mr-1.1.4/src/.libs/libdei80211mr.so

Example, simulation files (and one empty folder) to be copied : { bundle-test-large-scen.tcl, create-traffic-file.tcl, scen_n40_pt2_ms20_t5000_x2000_y2000, simulate_dtn.sh, Run1/ }.

Please note that the simulation time is an hour (or more).
Watch the trace file qtrace.tr : Will very slowly increase to ~9MB.

Result : ns-allinone-2.35/Run1/{ bundle_delays.tr, qtrace.tr, receipt_delays.tr }. The files can be used with Xgraph.
