How To Encrypt Data In Ns2 By Any Of Algorithm?

Hello everyone,
i would like to encrypt & decrypt data at the application level.
This data needs to be send to another device via wireless.I found one such cipher named ceaser cipher in the internet.But it looks weak and easy to be broken. Can someone suggest me robust cipher's concepts which can be done at application layer?

Hi,

I intend to use mannasim script generator tool to create mobile nodes for routing protocols like aodv, leach , dsdv and dsr.

To be best of my knowledge, WSN nodes in mannasim are assumed to be static but I would like to know if there is a resource available which explains how the tcl code can be modified to achieve node mobility.

I have tried searching google but I haven't gotten satisfying search result.

It seems is better to ask an experienced ns2/mannasim user.

Be sure your kind response is valued

Hi all,

I was wondering did anyone try running PEGASIS simulation on NS-2.34? I am using Ubuntu 10.04 and I tried running it with the LEACH+PEGASIS patch from exidus, but the pegasis output does not seem right, although the leach output seems fine.
As seen there is not data sent and the nodes alive stays 10 (used only 10 nodes) with energy still intact. Any input/thoughts are appreciated, thanks!

Hi All,

I have Redhat5.3 running on my machine. I have 800 GB data mounted on /dev/sdb1 partition. When I reboot my machine and after reboot the data is not available in /data folder. I have already use mount command but its not working.

Can anyone help me how to retrieve those data.

Please forgive me but I'm a little new to Red Hat (RHEL 5). I'm using rysnc to backup critical data and to a second disk; here is what I'm typing at the command line rsync -rvgal /data/disk1/share /data/backup/share. It appears that the softlinks are not transfered to the backup drive and some of the links point to data not located in the source folder (/data/share). After reading the rsync man page I was a little confused about the L option (vs the l option). In order to ensure that the linked files are moved should I type the below:

rsync -rvgaL /data/disk1/share /data/backup/share

A million thanks,
Johnny Mac

Experts,


I need your help to create malicious nodes for OLSR routing protocol. I completly patch OSLR in ns 2.35 in ubuntu 14.10 (32-bit) and its working but when I am try to create any malcious node by defining it "Malicious" or "hacker" it show me an error and not running that .tcl file.

for an example.

$ns_ at 0.0 "[$node_(8) set ragent_] hacker "
$ns_ at 0.0 "[$node_(14) set ragent_] hacker "
$ns_ at 0.0 "[$node_(20) set ragent_] hacker "
$ns_ at 0.0 "[$node_(26) set ragent_] hacker "



Help me to solve this problem.
I searched over internet but couldn't find any solution.

Help me to solve this.

Thank you.

will encrypting my audio data and burning it on a cd/dvd be worth it since the other person can copy it onto there pc? such as audio files for court? I know it can be copied as long as the pc reads it. but can I protect or encrypt its data as not to be altered when copied? if it is possible please do tell thanks in advance.

Hi all,
I am working on routing protocols in vanets. Can anyone provide me with relevant source code for implementation of routing protocols in vanets.

Hi All,

I am new to linux and I am finding difficulties in understanding the below commands.

Please explain what is happening in the below commands.

Code:

Please explain how this commands flows especially
exec 4< $BCP_DIR/cnts.data & exec 4<&-

Hi,

i wana implement the watchdog & pathrater on AODV protocol in MANETS for misbehaving nodes on NS2.35. I wana show its performance analysis via xgraph. I have added a malicious node on AODV protocol after that i couldnt figure out how can i implement watchdog and pathrater and show analysis via xgraph. I have chcked the similar threads here but it was for ns 2.34 but still i tried it and m getting errors. I downloaded the watchdog zip files and followed the instructions of text file of it. One more thing, is it necessary to set all nodes for promiscuous mode??I also need code for that. I put the watchdog-basic.zip folder in AODV folder which was inside of ns-2.35 but what should be the tcl script for watch dog i have aodv tcl file in which malicious node is added too. I am new to ns2 and linux. Please help anyone i urgently need answers.
