Do you guys want to know about the programming tactics in network simulator 3? If yes, the stay tuned with this article because our technical professionals have highlighted the process of writing programming code in Ns2.
Ns2 in Programming
The C++ and Tcl / Otcl are the programming languages that are deployed to perform the network simulation process based on ns2. For your reference, we have highlighted the sample code in Ns2
- C++ code to receive the ping broadcast request
printf(“Recv BRDCAST Ping REQ : at %d.%d from %d.%d\n”, here_.addr_, here_.port_, hdrip->saddr(), hdrip->sport());
Packet::free(pkt);
Packet* pktret = allocpkt();
hdr_ping* hdrret = hdr_ping::access(pktret);
hdr_ip* ipret = hdr_ip::access(pktret);
ipret->dport() = ipret->sport();
send(pktret, 0);
- Tcl for add agent id for all nodes
for {set i $val(nn)} {$i < $val(nn) } {incr i } {
$ns at 0.0 “[$node_($i) set ragent_] id”
}
Execute Ns2 Programming
We have to execute the below mentioned commands to implement the programming based on network simulator 2.
cd /home/research/NS2_in_programming
sudo ./ns Main.tcl
Finally, we have highlighted the result which is acquired through the implementation of Ns2 programming.
