How to find Residual Energy of the nodes in ns2


Hi all,

I am writing a tcl script for WSN in NS-2. In my script, I want to summary residual energy of each nodes in trace file .tr

I have googled some sites, but i does not works. I have seen also some thread in this forum but answer is not clear.

http://slogix.in/how-to-find-residua...e-nodes-in-ns2

https://ns2research.wordpress.com/20...rgy-of-a-node/

I followed second link, declare in aodv.h and add code into aodv.cc

Code:
double AODV::get_energy(nsaddr_t addr);
Code:
double AODV::get_energy(nsaddr_t addr) 
{
Node* thisnode = Node::get_node_by_address(addr);
double energy ;
energy = thisnode->energy_model()->energy();
return energy;
}
In tcl scrip, I also declare EnergyModel. However, I don't know how to call this function in tcl script

Code:
$ns node-config   -energyModel "EnergyModel" \
                   -initialEnergy 3.4 \
                   -txPower 0.33 \
                   -rxPower 0.1 \
                   -idlePower 0.05 \
                   -sleepPower 0.03 \
Code:
set energy [new Agent/AODV] ???
Thanks,
Khanh CN

Welcome to LQ.

Simulation examples, energy model : EnergyModel-examples.tar.gz
https://drive.google.com/file/d/0B7S...ew?usp=sharing

Example : $ ns aodv-Soumia.tcl → The trace file is simple.tr 25.9MB.

Lines with ``energy´´ in simple.tr :
$ grep energy simple.tr >> Energy.txt

Energy : $ awk -f energy-tes.awk simple.tr
The ~140 awk scripts https://drive.google.com/file/d/0B7S...ew?usp=sharing


About "double OLSR::get_energy(nsaddr_t addr);" (for OLSR.cc ?)
Probably of no use, unless you are using the OLSR protocol : umolsr-ns235_v1.0-2014.patch

Analyzing tool for energy, etc. : APP-Tool
https://github.com/WiNG-NITK/APP-Tool
.... See README.md

The result from simple.tr :
Code:
Average Residual Energy
Average residual energy  		:461.045223

---------------------
Residual Energy for particular node
Residual energy of node 0 is : 955.677067

Hi @knudfl, one more question.

Which is exactly .awk file to be used to analysis Packet Delivery Ratio after complete simulation.

Regards,

Re #5 : Please do not quote entire posts. A "one word reference" will do.

Packet Delivery Ratio : Usually PDR.awk → also included in "Top 20 scripts"
https://drive.google.com/file/d/0B7S...ew?usp=sharing
.... mostly awk scripts from APP-Tool.
