Code on how to Print Routing Table in AODV
Welcome back all readers. Generally in ns2 there are no automatic provisioning to print a routing table for a given
node in ns2. However, using the tracefile generated using ns2, routing
table can be printed, but one should be good enough in processing a file
using awk, python or any other scripts.
The following code will make you print the routing table when you are using AODV Protocol.
Files to be modified:
~ns-2.35/aodv/aodv.h
~ns-2.35/aodv/aodv.cc
The GREEN colored code indicates the addition of these lines in to the existing codes.
The following line can be added to the aodv.h file inside the class AODV
in the protected scope. probably add the line after the rt_down()
function.
void rt_print(nsaddr_t nodeid);
In the aodv.cc file, add the following entry anywhere, but probably after the end of rt_down() function.
void AODV::rt_print(nsaddr_t nodeid) {
FILE *fp;
fp = fopen("route_table.txt", "a");
aodv_rt_entry *rt;
for (rt=rtable.head();rt; rt = rt->rt_link.le_next) {
fprintf(fp,
"NODE: %i %f %i %i %i %i %i %f %d \n", nodeid, CURRENT_TIME,
rt->rt_dst, rt->rt_nexthop, rt->rt_hops, rt->rt_seqno,
rt->rt_expire, rt->rt_flags);
}
fclose(fp);
}
Here the above function records the routing table entry in to a file called route_table.txt.
The above code
step 1 creates a file pointer inturn a file called route_table.txt under append mode.
step 2 it creates an pointer to routing table entry.
- processes from the head of the queue to the last and print these information to the file with pointer fp Step 4 finally close the file pointer.
Finally the rt_print() function have to be called. This can be called from anywhere. Here is the function call in aodv.cc file.
It is inside the void AODV::recvReply(Packet *p) {
if (ih->daddr() == index) { // If I am the original source
// Update the route discovery latency statistics
// rp->rp_timestamp is the time of request origination
rt_print(index);
// print this nodes whole routing table
rt->rt_disc_latency[(unsigned char)rt->hist_indx] = (CURRENT_TIME - rp->rp_timestamp)
/ (double) rp->rp_hop_count;
// increment indx for next time
rt->hist_indx = (rt->hist_indx + 1) % MAX_HISTORY;
}
Once the above steps are done. Open the terminal and go to the ~ns-2.35. folder and type the following commands one by one
prompt$] make
Once the compilation is successful, test any of the wireless tcl files with AODV protocol is the routing and run it using ns filename.tcl
If you need a testing file, download here
Readers you can download the sample screenshot of the routing table

So here are the steps in Installing Tracegraph in Ubuntu 13.10
Ubuntu 13.10 is revamped with great features and also there are some limitations while installing 32 bit softwares in 64 bit OS.
So here are the steps in Installing Tracegraph in Ubuntu 13.10
Step1:- Download the Tracegraph.tar.gz file and copy it to the /home/username folder
Step2:- Enter the following commands one by one
Step3:- Untar it by entering the command, "tar xvzf tracegraph.tar.gz"
Step4:- cd tracegraph202
Step5:- ./trgraph (if this command gives you ./trgraph command not found, the follow the next step)
Step6:- sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 libxi6 libxtst6 libxrender1 libxtst6:i386 libXp6:i386 libXt6:i386
Step7:- The above command will fetch various libraries from the internet sources and downloaded and then try ./trgraph (you can see three windows popping out)
Important Note:
Don't forget to set the LD_LIBRARY_PATH for the shared object libraries as given below
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/username/tracegraph202/bin/glnx86/
If the path for NS2 is already set, the append this line to the existing LD_LIBRARY_PATH variable as given below
export LD_LIBRARY_PATH=/first/path:/second/path:/home/username/tracegraph202/bin/glnx86/
Downloading Youtube video based on Command in Fedora Linux

We all know how u (JNTU) ppl threated the jntuworld staff with the help of police & with ur money power and forced them to close the website. Shame on jntu.
I got to know that u (JNTU) with the help of some company forced to close JNTUWORLD so that u can start a website (Concept similar JNTUWORLD) & again loot the money from students in the name of some website. So u just stealing idea of students & u r making money. I even know how u took the convocation website from a student (a student who did as his final project in PG).
I really like to appreciate all the JNTUWORLD team who helped students alot in all ways. RIP JNTUWORLD
