Our well equipped research professionals have the enough knowledge about the execution of both the Ns2 and OTcl / Tcl script. Through that, we have derived this article for your ease.

Overview of Ns2

In general, Ns2 is denoted as the network simulator version 2 and it is the object oriented and discrete event driven simulator which is written using C++ and OTcl and Tcl. In this the C++ is deployed for detailed protocol implementation and OTcl is for the setup. Moreover, Ns2 is deployed to simulate the networks such as MANET, VANET and etc. In addition, it provides the simulation to routing and multicast protocols in both wired and wireless networks.

Source Code in Otcl / Tcl Script

For your ease, we can highlighted the Otcl / Tcl script source code for node configuration and that is used to create the Ns2 simulation file with the file extension of .tcl.

        $ns node-config -adhocRouting $val(rp) \

                   -llType $val(ll) \

                   -macType $val(mac) \

                   -ifqType $val(ifq) \

                   -ifqLen $val(ifqlen) \

                   -antType $val(ant) \

                   -propType $val(prop) \

                   -phyType $val(netif) \

                   -channelType $val(chan) \

                   -topoInstance $topo \

Run OTcl / Tcl Script File in Ns2

To run the OTcl / Tcl script file in network simulator 2, we have to implement the commands that have been highlighted in the following.

cd /home/research/tcl_in_ns2

sudo ./ns main.tcl
