Clone the Bitcoin Simulator. The Bitcoin Simulator is built on ns3 and it has been tested with versions 3.24 and 3.25. So, go to the official site and grab a suitable release. Detailed installation instructions for various platforms can be found here. https://www.nsnam.org/releases/ns-3-25/download/
Untar it with the following command:
tar xvfj ns-allinone-3.25.tar.bz2
For exhanging block messages, rapidjson is used. Download it from here. https://github.com/miloyip/rapidjson.git
Create a new directory named rapidjson under ns-allinone-3.xx/ns-3.xx and copy the contents of the directory include/rapidjson (from the downloaded rapidjson project in step 4) to the newly created rapidjson folder (ns-allinone-3.xx/ns-3.xx/rapidjson). You also have to copy all the files from Bitcoin-Simulation to the respective folders under ns-allinone-3.xx/ns-3.xx/. All the above can be done automatically by the provided copy-to-ns3.sh script.
Update the ns-allinone-3.xx/ns-3.xx/src/applications/wscript.
