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

Adding a malicious node in NS2 in AODV Protocol

Adding a malicious node is ns2 using aodv protocol. The node which is declared as malicious will simply drop the router packet (DROP_RTR_ROUTE_LOOP). Two files have to be modified. 1. aodv.h 2. aodv.cc aodv.h file changes Declare a boolean variable malicious as shown below in the protected scope in the class AODV bool malicious; aodv.cc file changes 1. Initialize the malicious varible with a value "false". Declare it inside the constructor as shown below AODV::AODV(nsaddr_t id):Agent(PT_AODV)... { ....... malicious = false; } 2. Add the following statement to the aodv.cc file in the "if(argc==2)" statment. if(strcmp(argv[1], "malicious") == 0) {     malicious = true;    return TCL_OK; } 3. Implement the behavior of the malicious node by setting the following code in the rt_resolve(Packet *p) function. The malicious node will simply drop the packet as indicated below. if(malicious==true) { drop(p,DROP_RTR_ROUTE_LOOP); } Onc
