Leach protocol installation in network simulator 2

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. 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:

********************************************************************

can't read "env(RCA_LIBRARY)": no such variable

    while executing

"source $env(RCA_LIBRARY)/ns-ranode.tcl"

    (file "mit/uAMPS/sims/uamps.tcl" line 9)

      ......................

      .....Code Omitted.....

      ......................

      (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 '#'):

Code:

********************************************************************

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

Now again remake and look at the correct energy
