Obtaining Node Position and Energy Dynamically in NS2.34

[thiru pathi]

I will be modifying the sample script simple-wireless.tcl found at ~/
ns-allinone-2.34/ns-2.34/tcl/ex and all my tasks in ns2 would be based
on AODV protocol.

1. In simple-wireless.tcl, change the routing protocol to AODV, enable
Energy model and set the initial energy value.

2. In the node configuration set the EnergyModel, Initial Energy
value, power spent in receiving mode,transmit mode,idle mode and sleep
mode.

3. Now we will move to the backend code(c++). Our edits would be
performed only in aodv.cc and aodv.h.

4. In aodv.h,first include the following header file that contains the
procedures/functions needed to access node postion,energy and several
other functions.

#include <mobilenode.h>


You will find class AODV, something like the one shown below.

5. In that, declare the following variables in “protected” scope.



* History management
*/

double PerHopTime(tprp_rt_entry *rt);


nsaddr_t index; // IP Address of this
node
u_int32_t seqno; // Sequence Number
int bid; // Broadcast ID
public:
double xpos ;
double ypos;
double zpos ;
double iEnergy;
MobileNode *iNode;


With that, no more work to be done in aodv.h. What we have actually
done here is to declare the variables that we will using in aodv.cc to
record a nodes position and energy.

6. In aodv.cc, we will initialize the variables that we have just
declared in aodv.h. This we do in the AODV “constructor“(invoked only
once during node creation).



xpos = 0.0;
ypos = 0.0;
zpos = 0.0;
MobileNode *iNode;
iEnergy = 1000.0;

7. Next, we include the code to access the functions in mobilenode.h,
that fetch the nodes current position and energy.



/*
Packet Transmission Routines
*/

void
TPRP::forward(tprp_rt_entry *rt, Packet *p, double delay) {
struct hdr_cmn *ch = HDR_CMN(p);
struct hdr_ip *ih = HDR_IP(p);

iNode = (MobileNode *) (Node::get_node_by_address (index) );
xpos = iNode->X();
ypos = iNode->Y();
iEnergy = iNode->energy_model()->energy();
printf("at Time (%.6f), Posotion of %d is X =%.4f and Y =%.4f
\n",CURRENT_TIME,index,xpos,ypos);
printf("at Time (%.6f): Updated Energy for node %d is Energy %.4f
\n",CURRENT_TIME,index,iEnergy);

fprintf(stderr,"\nPosotion of is X =%.4f and Y =%.4f \n",xpos,ypos);
fprintf(stderr,"Updated Energy for node is Energy %.4f
\n",iEnergy--);

fprintf(stderr,"N (%.6f): Routing agent is initialized for node %d
\n", CURRENT_TIME, index);

//fprintf(stderr, "\nNODE: \t %i\t %i\t %i\t %i\t %i\t %.4lf\t %d
\n",rt->rt_dst, rt->rt_nexthop, rt->rt_hops, rt->rt_seqno, rt-
>rt_expire, rt->rt_flags);



I have included that code AODV::forward() function, so that the nodes
position and energy are printed each time it forwards a packet. Where
and When you want them to be printed is your choice. Alternatively,
you may have the code included in the function of your choice and have
the output redirected to a file.

8. Thats all! All we have to do now is to run simple-wireless.tcl
$ns simple-wireless.tcl

[madhav kumar]

hi i done as per the above steps..., 

now while i am running a tcl file with AODV it is giving a segmentation fault..., error...,

n can u plz tell me how to write in tcl file to print the node position and energy 

for ex: position of node 1 is: x:____ y:_____
energy of node 1 is: ___________
.
.
.
.

[madhav kumar]

plz reply me its urgent...,

[hassan fadaie]

use mobilenode.h

[madhav kumar]

actually i am fresher i am not getting how to write the ttcl sccript for getting teh node position and energy...,

can u plz help me

if u have any code plz mail me .. plz...,

madhav...@gmail.com

--with regards

[Sanjeev K. Prasad]

when I am running this code, It gives segmentation fault.

pls tell me what is the problem?

[rohit patil]

i have done whatever you have told here, still it throws an error at assigning values to variable iNode as multiple markers at the line
 thank you.... 

[Foram Patel]

Hello,
I have done all this steps. But when I am running tcl file it gives segmentation dump error. Please help

[knudfl]

@Foram Patel ,   Hi.

All the default scripts with the name "wireless***.tcl will usually cause 'Segmentation fault', when edited to AODV.

?  Did you remember recompiling ns2 with the changes ? 
?  And save the new executable 'ns' to a new name :
$ cd ns-2.3x/ && cp ns ns-aodv && sudo copy ns-aodv /usr/local/bin/
.... All (AODV) simulations can then be run with $ ns-aodv file.tcl

AODV files (wireless) not causing 'Segmentation fault' are : ns2.3x/tcl/ex/wpan/wpan_demo*.tcl

[Anamika Garg]

Hello all,

I have setup energy model and it is working fine but i want that when node energy less than perticular threshold then AODV select path of that node whose energy is higher than that threshold value.

Please give me code its really very important for me. 

[hepzi prakash]

do you have that code mam, that below threshold energy in route path, the src node selects alternative path?

[Deachan Choskit]

Sir @Thirupatti
i am using ns2.35. As you have mentioned in your second step that we need to enable the Energy model , but in ns2.35 i didnot find the Energy Model in the simple-wireless.tcl. In ns2.35 is it not available or what?

[paras narkhede]

i want to calculate the energy of entire path so how to do that?

You can attach your code, not as aodv.tcl :  Already several files with that name.

I.e. a new file must have a new unique file name, e.g.  Arief-energy.tcl .

hi knudlf
my code in attach.
i want to ask about energy model in https://www.isi.edu/nsnam/ns/doc/node225.html, where do i add energy model class?is there in aodv.cc,is not it?

[knudfl]

@Arief Hidayat ,  Hi.

The ns2 doc https://www.isi.edu/nsnam/ns/doc/index.html

... is not about adding C++ code, but about the existing code.

EnergyModel is present in all versions of ns2. See attachments.

( EnergyModel → mac/ and mobile/ ).

About your errors : Seems you are trying to add EnergyModel to a basic simulation.

→ "aodv18.tcl" : https://drive.google.com/file/d/1uOvyXih1W2PDPP-2LYOJw4lYzSTRWPAd/view?usp=sharing

I made an example:

Added some aodv-Soumia.tcl code to your file → new file = Arief-energy-2.tcl

Please read my posts carefully, and notice that I am using $ ns235-64-orig Arief-energy-2.tcl

Some EnergyModel examples can run with the `ns235-aodv+´ executable, others not.

hi knudlf

i has followed the instructor based on https://getch.wordpress.com/2011/02/08/obtaining-node-position-and-energy-dynamically-in-ns2/, when i run the program, printf("at Time (%.6f), Position of %d is X: %.4f and Y : %.4f \n", CURRENT_TIME, index, xpos, ypos);
printf("at Time (%.6f), Update Energy for Node %d is Energy %.4f  \n", CURRENT_TIME, index, iEnergy);

these not appear, like as below :

»» awk: cannot open throughput.awk «« :  Which simulation is it about ?

»» when i run the program «« :  Unknown program.

Errors / question make no sense when the simulation command is missing.

My test :

$ ns235-aodv-rtable-WP-64 WP-aodv-rtable.tcl

... The files aodv.nam  326.0kB, aodv.tr 1.4MB, rtable.txt 8.6kB are created.
