regarding implementation of AODV-GAF protocol

abhi.samyak · 04-12-2014, 01:13 AM

I am working on my final year project on energy efficient routing in MANET's. In this regard i needed implementation details regarding AODV-GAF protocol. Please if anyone who Knows about it guide me in this issue. Thanking in advance

GAF is already present in all ns-2.xx :
CHANGES.html: Add GAF algorithm (for AODV and DSR) into ns → → May 15´ 2000.

Code:

[knudfl@localhost ns-2.35]$ grep -iRn gaf *
aodv/aodv.cc:1030:   // assert(ch->ptype() == PT_AODV); // maybe a diff pkt type like gaf
aomdv/aomdv.cc:1384:                     // assert(ch->ptype() == PT_AODV); // maybe a diff pkt type like gaf
aomdv/aomdv.cc:1832:                     // assert(ch->ptype() == PT_AODV); // maybe a diff pkt type like gaf
CHANGES.html:1888:<pre>Add GAF algorithm (for AODV and DSR) into ns
common/packet.h:151:        // GAF packet
common/packet.h:152:static const packet_t PT_GAF = 49;
common/packet.h:370:            // for GAF
common/packet.h:371:                name_[PT_GAF] = "gaf";
Binary file doc/everything.pdf matches

dsr/dsragent.cc:605:  // special process for GAF

FILES:624:gaf/gaf.cc
FILES:625:gaf/gaf.h
.
tcl/test/test-suite-wireless-lan-gaf.tcl

How to use "GAF/AODV" ? I guess you will have to read some pdf`s etc ..

Thanks for replaying back @knudfl

sorry for replaying back late... I went through the links you have mentioned but in particular I didnt find exact procedure to implement GAF on AODV/DSR

please help me in this regard ... Thanking in advance

Please continue reading about GAF : ns2 doesn't come easy.

Google, ns2 gaf.tcl https://www.google.com/webhp?hl=all#...q=ns2+gaf.tcl+
... to find some hints about using GAF in your simulation.

thanks @knudfl

I went through the links mentioned by you. I have changed test-suite-wireless-lan-gaf.tcl as per my simulation scenario and tests performed as instructed in read me file and test-all-lan files present in the ns-2.34/tcl/test folder but when i run by command
#code
././test-all-wireless-lan-gaf
#output
no saved test output. do cvs update -d
or re-run your test with "new" as the last argument
as output ... not getting what to do ???
Please help me in this regard. Thanking in advance

$ cd ns-allinone-2.34/ns-2.34/tcl/test/
$ ./test-all-wireless-lan-gaf > 1-test-all-wireless-lan-gaf.txt
... if you want to save some text. ( 538B ).

Much more content in the other output files :

thank you @knudfl for helping actually your replies are boosting my confidence to try out the possibilities

Somehow I am able to generate the trace file and nam output files now .But when I try to find out the other performance factors such as in case of Packet Delivery Fraction (PDF) using awk scripts i'm getting output as shown below,
#output
cbr s:4886 r:12072, r/s Ratio:2.4707, f:0 (s= sent pkts, r=received pkts, f= forwarded pkts)

I am little confused whether above values are correct?
How can number of received packets can exceed number of sent packets? is it possible to have PDF > 1?
please help me in this regard

thanking in advance

@knudfl I beg your pardon for multiple posts back to back I forgot to mention another problem that is I am not getting End to End delay ,Throughput and other parameters when I run awk scripts. In the trace file there is neither cbr packets were transmitted or received and no packets were generated at RTR level in whole simulation, my whole trace output contains lines as shown below
either
#output
r 131.184803877 _41_ AGT --- 349 gaf 40 [0 ffffffff 2f 800] [energy 448.132172 ei 51.789 es 0.000 et 0.014 er 0.065] ------- [47:254 41:254 32 0]
or
#output
s 131.184803877 _41_ AGT --- 349 gaf 40 [0 ffffffff 2f 800] [energy 448.132172 ei 51.789 es 0.000 et 0.014 er 0.065] ------- [47:254 41:254 32 0]

Can you please tell me why I am not getting the cbr packets or packets at RTR level?

Please help me in this regard sir

Thanking in advance

May be you will have to write a dedicated awk script ?

Please have a look at the already existing scripts ...

thanks @knudfl

you have already given that link on one of my other thread

I think I didnt clarify the problem i'm facing in earlier posts. The problem in my simulation scenario are
1. the packets are generated and processed only at the AGT level and no packets at RTR level
2. the cbr packets were no where in the output
3. other problem is about number of received packets please refer the post #7

Thanking in advance
