Multiple Versions of ns3 in Ubuntu 22.04 In this post, we are going to install two versions of ns3 namely ns-3.35 and ns-3.37 My OS is : Ubuntu 22.04 LTS (Long Term Support) ns-3.35 uses waf and (./waf --run scratch/first) ns-3.37 uses cmake (./ns3 run scratch/first.cc) So we will install both the packages Go through the video for complete instructions To start with $ sudo apt update $ sudo apt install build-essential autoconf automake libxmu-dev g++ python3 python3-dev pkg-config sqlite3 cmake python3-setuptools git qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools gir1.2-goocanvas-2.0 python3-gi python3-gi-cairo python3-pygraphviz gir1.2-gtk-3.0 ipython3 openmpi-bin openmpi-common openmpi-doc libopenmpi-dev autoconf cvs bzr unrar gsl-bin libgsl-dev libgslcblas0 wireshark tcpdump sqlite sqlite3 libsqlite3-dev libxml2 libxml2-dev libc6-dev libc6-dev-i386 libclang-dev llvm-dev automake python3-pip libxml2 libxml2-dev libboost-all-dev I have downloaded both the versions of ns3 fr
AWK Scripts are very good in processing the data from the log (trace files) which we get from NS2. If you want to process the trace file manually, here is the detail Here is a sample of trace file from NS2 (However ns2 supports a new type of trace file also), but this post will make you understand the old trace format only. r 0.030085562 _0_ MAC --- 0 message 32 [0 ffffffff 1 800] ------- [1:255 -1:255 32 0] r 0.030110562 _0_ RTR --- 0 message 32 [0 ffffffff 1 800] ------- [1:255 -1:255 32 0] s 1.119926192 _0_ RTR --- 1 message 32 [0 0 0 0] ------- [0:255 -1:255 32 0] AWK Scripts are very good in processing the data column wise. For example the first column in the above trace file represents r, s which indicates receive, sent respectively. If we want to trace the entire r and s alone from this trace file we can represent it as $1 So $1 represents ACTION $2 Time $3 Node ID $4 Layer $5 Flags $6 seqno $7 type $8 Size $14 Energy (if the network nodes includes EnergyModel) To run t
