Essentially a duplicate of your other thread:
https://www.linuxquestions.org/quest...ol-4175733095/

At some point, you're going to have to do research on your own for your own homework. We aren't going to type up step-by-step instructions for you or look up things and give you links. There are several threads on this very site that answer this, along with many on any search-engine for "ns2.35 zrp encryption patch". Start there.

The ns2 "Security" is not a genuine encryption, but is a very simple code.
security_ns235.patch
https://drive.google.com/file/d/0B7S...ew?usp=sharing

Patching an ns-2.35 which is already patched with zrp :

Code:

cd ns-allinone-2.35/
patch -p0 < security_ns235.patch

.... There is one file to edit: common/packet.h → Edit to

Code:

   203	static const packet_t PT_ZRP = 73; // [CHANGE-2(for_ZRP-AGENT) : Lines#2]
   204	
   205	static const packet_t PT_SECURITY_PACKET = 74;
   206		
   207	        // insert new packet types here
   208	static packet_t       PT_NTYPE = 75; // This MUST be the LAST one

For encryption, suggest code like "aodv + SSL" → saodv-with-ssl_ns235.diff
https://drive.google.com/file/d/1GCg...usp=drive_link
.... which is this in aodv.cc: +#include <openssl/aes.h> +#include <openssl/ec.h>
and Makefile.in (line 23) + -lcrypto @LIBS@ -lssl @LIBS@
? Might work with ZRP? zrp.cc ?

@knudfl so I tried to patch an ns-2.35 which is already patched with zrp as you have mentioned above and while running the

Code:

patch -p0 < security_ns235.patch

it shows me this error:

i edited the packet.h file as you have stated. I am not sure why is it showing failed. I have tried multiple times it shows the same

Re #4

The zrp + security sequence ....

Code:

tar xvf ns-allinone-2.35_gcc5.tar.gz
https://drive.google.com/file/d/0B7S...FDb7ul0VFk6FZQ
cd ns-allinone-2.35/
patch -p0 < zrp-ns235.patch
patch -p0 < security_ns235.patch
export CC=gcc-4.8 CXX=g++-4.8 && ./install
cd ns-2.35/
cp ns ns235-zrp+security
sudo cp ns235-zrp+security /usr/local/bin/

The packet.h.rej and the "patch.log" https://drive.google.com/drive/folde...usp=drive_link

Sorry, you will also have to add

Code:

		name_[PT_SECURITY_PACKET]= "Security_packet";

... to line ~333 in packet.h, see packet.h.rej
(So no real errors during patching but the 2 edits in common/packet.h)

Alternatively, you can setup a new ns-allinone-2.35/ in a new folder in /home/name/ns2/, and use the new patch zrp+security_ns235.patch
https://docs.google.com/document/d/1...usp=share_link
i.e. you can have as many ns-allinone-2.xx as you want installed at the same time.

The example zrp_guindy-Security.tcl (+ mobility31) is also included in https://drive.google.com/drive/folde...usp=drive_link
