Leach protocol installation in ns2 had to go through the following steps:
As far as I have studied, I got two patches for Leach
1. Download ns-234-leach.tar.gz. Keep this in your /home/$userID/ns-allinone-2.34/ns-2.34. (Assuming you ns-allinone is in home dir)
Leach ns2.34
2.Download the bash file "leach-setup.sh" into the directory " /home/$userID/ns-allinone-2.34/ns-2.34".
leach-sh
3- Now find /home/arun/ns-allinone-2.35/ns-2.35 in the leach-setup.sh file and replace it with your own path.
/home/$username/ns-allinone-2.34/ns-2.34
CC = gcc-4.3
CPP = g++-4.3(Not necessary. I did not need to )
7- run the following commands
wsn@ubuntu:/home/$username/ns-allinone-2.34/ns-2.34$./configure
wsn@ubuntu/home/$username/ns-allinone-2.34/ns-2.34$make clean
wsn@ubuntu/home/$username/ns-allinone-2.34/ns-2.34$make
[trace/cmu-trace.cc: In member function ‘void CMUTrace::format(Packet*, const char*)’:
trace/cmu-trace.cc:1327: error: ‘format_rca’ was not declared in this scope.] then you need to find these lines.. in /ns-allinone-2.34/ns-2.34/trace/cmu-trace.h
void format_imep(Packet *p, int offset);
void format_aodv(Packet *p, int offset);
void format_aomdv(Packet *p, int offset);
After this lines add...........
#ifdef MIT_uAMPS
void format_rca(Packet *p, int offset);
#endif
#ifdef MIT_uAMPS
#define ADV_CHAR 'A'
#define REQ_CHAR 'R'
#define DATA_CHAR 'D'
#endif
and also add this line into /home/anupama/ns-allinone-2.34/ns-2.34/tcl/lib/ns-default.tcl (line 765):
# ——————————————————
Phy/WirelessPhy set alive_ 1
Phy/WirelessPhy set Efriss_amp_ 100e-12
Phy/WirelessPhy set Etwo_ray_amp_ 0.013e-12
Phy/WirelessPhy set EXcvr_ 50e-9
Phy/WirelessPhy set sleep_ 0
Phy/WirelessPhy set ss_ 1
Phy/WirelessPhy set dist_ 0
# ——————————————————
9. Now again do a make
wsn@ubuntu/home/$username/ns-allinone-2.34/ns-2.34$make
wsn@ubuntu/home/$username/ns-allinone-2.34/ns-2.34$bash ./test
Now go to ns-allinone-2.34/ns-2.34/mit/leach_sims/leach.out
Probably there will be errors in leach.err
Now for that
As far as I have studied, I got two patches for Leach
1. MIT patch
2. Mannasim patch- I didnt work much with it but if you dont want to meddle much with tcl, you can use it.
Ok, the prerequisite is Ubuntu 10.04. We need to install ns-2.34 over that because LEACH MIT patch was made in 2000. Its a little painful to use the old OS, but it has to be done. Again you can have your OS on a virtual box on windows (only if you are not concerned with speed and not in love with your computer). 1. Download ns-234-leach.tar.gz. Keep this in your /home/$userID/ns-allinone-2.34/ns-2.34. (Assuming you ns-allinone is in home dir)
Leach ns2.34
2.Download the bash file "leach-setup.sh" into the directory " /home/$userID/ns-allinone-2.34/ns-2.34".
leach-sh
3- Now find /home/arun/ns-allinone-2.35/ns-2.35 in the leach-setup.sh file and replace it with your own path.
/home/$username/ns-allinone-2.34/ns-2.34
4- Move to the directory "/home/$username/ns-allinone-2.34/ns-2.34" and patch the file "leach-setup.sh"
just write$ bash leach-setup.sh
5- Now you need to edit Makefile.in and Makefile. Go to /home/$username/ns-allinone-2.34/ns-2.34 where you will find these files
6. Edit both “Makefile” & “Makefile.in” as following:CC = gcc-4.3
CPP = g++-4.3(Not necessary. I did not need to )
7- run the following commands
wsn@ubuntu:/home/$username/ns-allinone-2.34/ns-2.34$./configure
wsn@ubuntu/home/$username/ns-allinone-2.34/ns-2.34$make clean
wsn@ubuntu/home/$username/ns-allinone-2.34/ns-2.34$make
7- If the previous commands passed successfully then you are ready to test your "Leach" by running bash ./test:
wsn@ubuntu:/home/$username/ns-allinone-2.34/ns-2.34$bash ./test
8. If you get errors in the terminal as [trace/cmu-trace.cc: In member function ‘void CMUTrace::format(Packet*, const char*)’:
trace/cmu-trace.cc:1327: error: ‘format_rca’ was not declared in this scope.] then you need to find these lines.. in /ns-allinone-2.34/ns-2.34/trace/cmu-trace.h
void format_imep(Packet *p, int offset);
void format_aodv(Packet *p, int offset);
void format_aomdv(Packet *p, int offset);
After this lines add...........
#ifdef MIT_uAMPS
void format_rca(Packet *p, int offset);
#endif
#ifdef MIT_uAMPS
#define ADV_CHAR 'A'
#define REQ_CHAR 'R'
#define DATA_CHAR 'D'
#endif
and also add this line into /home/anupama/ns-allinone-2.34/ns-2.34/tcl/lib/ns-default.tcl (line 765):
# ——————————————————
Phy/WirelessPhy set alive_ 1
Phy/WirelessPhy set Efriss_amp_ 100e-12
Phy/WirelessPhy set Etwo_ray_amp_ 0.013e-12
Phy/WirelessPhy set EXcvr_ 50e-9
Phy/WirelessPhy set sleep_ 0
Phy/WirelessPhy set ss_ 1
Phy/WirelessPhy set dist_ 0
# ——————————————————
9. Now again do a make
wsn@ubuntu/home/$username/ns-allinone-2.34/ns-2.34$make
wsn@ubuntu/home/$username/ns-allinone-2.34/ns-2.34$bash ./test
Now go to ns-allinone-2.34/ns-2.34/mit/leach_sims/leach.out
Probably there will be errors in leach.err
You may get few errors in the leach.err file as follows:
********************************************************************

(procedure "source" line 8)
invoked from within
"source tcl/mobility/$opt(rp).tcl"
(file "tcl/ex/wireless.tcl" line 187)
********************************************************************
Now for that
The problem is in the path. What modify all the paths in
“ns-allinone-2.34/ns-2.34/mit/uAMPS/sims/uamps.tcl”. Here is the
modified code below the commented out lines (lines beginning with '#'):

********************************************************************
Replace anupama with your username.
Again do a bash ./test and hopefully you will get the results in leach.out.
**********************************************************
Now if you want to have a look on the leach-c results, go to file
/home/$username/ns-allinone-2.34/ns-2.34/leach_test
Here you can just replace leach with leach-c and see results of leach-c too.
Again the energy values in this patch is not correct. For making it correct,
In \mac\Wireless-Phy.cc:
Code:
if (energy_)
{
if(alive_ != 0) // Deepa
{
if (energy_->remove(pktEnergy(Pt_, PXcvr_, ch->size())) != 0)
{
printf("alive = 0\n");
alive_ = 0;
}
} // Deepa
}
i.e., add the <code> if(alive_ != 0) </code> wherever the remove energy function is called,
and in mit\rca\energy.cc :
Code:
int EnergyResource::remove(double amount)
{
double new_level = energy_level_ - amount;
if(new_level >= 0 )
{
energy_level_ = new_level;
expended_ += amount;
} // Deepa
Code:
if (energy_)
{
if(alive_ != 0) // Deepa
{
if (energy_->remove(pktEnergy(Pt_, PXcvr_, ch->size())) != 0)
{
printf("alive = 0\n");
alive_ = 0;
}
} // Deepa
}
i.e., add the <code> if(alive_ != 0) </code> wherever the remove energy function is called,
and in mit\rca\energy.cc :
Code:
int EnergyResource::remove(double amount)
{
double new_level = energy_level_ - amount;
if(new_level >= 0 )
{
energy_level_ = new_level;
expended_ += amount;
} // Deepa
Now again remake and look at the correct energy
