Re #59, #60.

All copies of wireless-gpsr.tcl that I have :
1) Time stamp = Friday 02 Dec 2005.
2) File size = 8.6kB = 8815B. And have 8,815 characters.

* If you are using the right OS for GPSR : No errors.
See https://drive.google.com/file/d/0B7S...ew?usp=sharing

I use the same tcl file ( wireless-gpsr.tcl), but i don't have the same result that you have (trace file)...

i use ubuntu 12.04 (with ns2.35) and normally must walk, but not yet ....

Ubuntu 12.04 -32 : I updated libc6, and created a new 'ns235-GPSR-K-2017'.

$ ns235-GPSR-K-2017 wireless-gpsr.tcl : trace.tr = 5.1MB
... Uploaded as GPSR-Ubuntu12-KeLiu-trace.tr.txt

To create a proper executable 'ns235-gpsr-keliu' you will have to start from scratch in a new folder:
tar xvf ns-allinone-2.35_gcc482.tar.gz , etc. etc.

If you cannot get a better result, use the package 'gpsr-keliu-ns-2.34-ubuntu10_i386.deb'
https://drive.google.com/file/d/0B7S...ew?usp=sharing
.. provides /usr/local/bin/ns-gpsr-k

Hi knudfl,

Thank you very much for reply.
I hope you are well.
I have tested with package gpsr-keliu-ns-2.34-ubuntu10_i386.deb 'but no results. The gpsr protocol appears in the trace.tr file with GPSR-HLS but not with Keliu (always undefined ...).
It seems to me that the format of the file trace is generic for gpsr. So how to calculate the parameters of the PDR, delay, ... in the file awk.
pleaaaase,if you have an example of the AWK file that calculates QoS parameters (PDR, delay, jitter, ....) to see if my file trace.tr it works and gives results.

Thank you in advance.

Re #35.

As you can see from "GPSR-Ubuntu12-KeLiu-trace.tr.txt"
https://drive.google.com/file/d/0B7S...ew?usp=sharing
... I have lots of lines with "gpsr".


* 130 awk scripts, see awk#perl#python__scripts-1-2017.tar.gz

PDR : PDR.awk, PacketDeliveryRatio.awk

Jitter : jitter_.awk, Avg_Jit.awk, Avg_Jit_Flow.awk, instantJitter2005.awk, instantJitter2009.awk, Instnt_Jit.awk, Instnt_Jit_Flow.awk, Jitter2007.awk, intervalo_confianca_delay_-_jitter_maximo.awk, measure-jitter.awk

Delay : End-to-End-Delay.awk, End-to-End-Delay##.pl, delay.awk, delay-e2e.awk, delay_alterado_einar.awk, delay_-_jitter_alterado_einar.awk, delay-link.awk, delay_original.awk, e2edelay.awk, en2end-delay.awk, Endtoenddelay.awk, insdelay_tcp-cbr-vbr.awk, measure-delay.awk, thr_drop_delay.awk

Thank you, but most of them do the test on cbr traffic or AODV, there is not a specification for the format of the gpsr protocol.

Re #66, #64.

You have four GPSR scripts in "hls/utils/" :
evaluate.pl, evFromdirectory.pl, gls_evaluate.pl, runfromdirectory.pl

Hi sir,

Thank you so much knudfl for your help.

I will restart the simulation.

I have installed CentOS6.7 -i386 and I exactly follow the instructions related to install & patch gpsr-hls
when I'm going to simulate 'ns2.35/tcl/mobility/gpsr.tcl' I get this ..

[samer@centos6 mobility]$ ns235-gpsr-hls-el6 gpsr.tcl
missing close-brace: possible unbalanced brace in comment
while executing
"proc gpsr-create-mobile-node { id args } {
global ns ns_ chan prop topo tracefd opt node_

set ns_ [Simulator instance]
# ->
#if {..."
(file "gpsr.tcl" line 129)
[samer@centos6 mobility]$

Post #69, @saz1985 : Welcome to LQ.

'ns2.35/tcl/mobility/gpsr.tcl' : Please read the file to know it's not a simulation.
'ns2.35/tcl/mobility/gpsr.tcl' is a configuration file !

thanks knudfl .. but I'm very confused.
first of all, how could I simulate GPSR protocol not an example?
secondly, are these examples using gpsr.h and gpsr.cc?
thirdly, where and which files could I make some modifications on it to enhance GPSR?
finaly, how could I show results to make comparison?
I know it's take time to answer but I'm new in ns2. So could you please guide me?

Re #71.
GPSR-hls simulations are done with the examples linked in #70.
Repeat : 'ns2.35/tcl/mobility/gpsr.tcl' is not an example.


All C++ functions (and tcl/lib/ns** ) are compiled into one file:
The executable 'ns' (ns235-gpsr-hls-el6). No C++ code is used.
See ns2-INFO.txt https://drive.google.com/file/d/1FCj...ew?usp=sharing


I know no examples of modifications to GPSR-hls. And you are probably the first one to ask about this.


Comparison between GPSR-hls and GPSR-hls-modified ?
You can have as many ns-allinone-2.xx as you want, installed at the same time.
Easy to have multiple "ns-name" :
/usr/local/bin/{ns235-gpsr-hls-el6, ns234-hls-modified}, etc. etc.
See ns2-INFO.txt

Note : You cannot build ns-2.35 + GPSR-hls with a 64bits OS. ns-2.34 must be used.

Dear knudfl

sorry, but I'm asking about how can I simulate the original GPSR and modify its code (not GPSR-hls)
GPSR-hls focus on increasing packet delivery ratio (decrease data loss)
I've some ideas and I want to implement it on original GPSR to reduce overhead without using HLS .. is it possible ??

big thanks

Re #73.

Alternatively, please have a look at "GPSR-KeLiu", which is gpsr only.

Dear knudfl

Can you provide me with any editor can help to trace c++ coding for ns2 on CentOS (like visual studio on windows), so I can edit c++ files easily ?

Thanks your effort
