Radio Environment map+lena-dual-stripe.cc

[networksim...@gmail.com]

Hello

I want to provide figure 1 from lena-dual-stripe. So, First i enable REM, by changing false to true, according:

static ns3::GlobalValue g_generateRem ("generateRem",

                                       "if true, will generate a REM and then abort the simulation;"

                                       "if false, will run the simulation normally (without generating any REM)",

                                       ns3::BooleanValue (false),

                                       ns3::MakeBooleanChecker ());

 second i run the lena-dual-stripe.cc in terminal and it runs successfully, third by text file obtained as output i apply this script in gnuplot:

set view map;

set xlabel "X"

set ylabel "Y"

set cblabel "SINR (dB)"

unset key

plot "lena-dual-stripe.dat" using ($1):($2):(10*log10($4)) with image

at the end i get figure 2, But my purpose is getting figure 1.

How can resolve it?

How can get figure 1 exactly?

Thanks.

Did you try changing the resolution and other parameters of REM helper?

Hello

I Apply These Codes(The File is Attached Here), And As I Said, I Get Figure 2 but not Figure 1.

How Can I Resolve This Problem? And What values should take into account as input? Do The Lines From 827 To 835 Wrong?

Thanks

Hi,

the documentation does not say that if you just run lena-dual-stripe with the default parameters that you will get exactly the same map. It just shows an example of a single run of specific parameters. In order to create the same or similar map you need to carefully configure both dual-stripe scenario and rem helper. In the documentation for REM you may find the reason why this specific configuration of REM map is not generated by default when running lena-dual-stripe example. The map that is by default generated when running lena-dual-stripe scenario is a low resolution map that is showing the macros and buildings. I attach the figure.

Please go again through the documentation about Rem environment maps:
ttps://www.nsnam.org/docs/models/html/lte-user.html#radio-environment-maps

Then also check https://www.nsnam.org/docs/models/html/lte-user.html#reference-scenarios to see all the parameters of dual-stripe.

First, you should make sure what are coordinates of macros, buildings and eNodeBs. It will probably help you to draw it on a paper first. Then think about which part of map you would like to have on your REM map. Then configure x and y coordinates of REM map, and resolution. Also check the index of RB. Also, seems that you are not using the latest lena-dual-stripe code.

Cheers,

Biljana
