encryption schemes implementation in NS-2

[anup mandlekar]

Hey

I'm currently learning ns-2. I basically need to implement various
encryption schemes such as AES, blowfish, RC-2, XTEA on a simple
wireless-cum-wired network using NS-2. And study the corresponding
parameters such throughput (number of bytes encrypted(or decrypted)/time for
encryption(or decryption)), computation overhead, memory overhead etc.

can you please let me know how do i implement encryption (lets say AES) at
any particular node? and is it possible for me to find computation overhead,
memory overhead by analysing ns-2 trace files? if yes, how?

Thanks,
