What Language is Ns2

Here, our well experienced research professionals provide the notable assistance for the research scholars. Moreover, this article is about the utilization of languages in network simulator 2.

Languages in Ns2

Most significantly, network simulator 2 is defined as the open source software and it is written in two main languages such as,

  • C++
  • It is deployed to schedule and execute the events
  • It maintains the state of network
  • It handles the low level details such as
  • Bit level manipulation
  • Packet processing
  • Object oriented tool commands language (OTcl)
  • It is defined as the extension of tool command language (Tcl)
  • It is used for the creation and control of network entities and the configuration of network scenarios in network simulator 2

Simulation Code in Ns2

For your reference, our technical professionals have highlighted the sample source code using both the above mentioned languages.

  • Otcl code for CBR traffic source using UDP

                        set udp0 [new Agent/UDP]

                        $ns attach-agent $n0 $udp0

                        set cbr0 [new Application/Traffic/CBR]

                        $cbr0 attach-agent $udp0

                        $cbr0 set packet_size_ 512

  • C++ code to update link state

            LsLinkStateList * LSLptr = findPtr (nodeId);

                                    if (LSLptr == NULL) {

                                    insert(nodeId, linkStateList);

                                    return true;
