Hello Ayoub,

I have worked on TCP, WSNs, MANETs and VANETs. In general I would say

1. Complicated - Modifying the underlying protocol and writing your own algorithms

2. Time consuming - Large scale simulations involving hundreds of nodes

Interesting.

I think creation or simulation of a wireless network in NS 2 is very tedious, instead of NS2 u can use Caulnet simulator.

SATCOM MFTDMA DAMA simulations of a network with up to two hundred terminals with ns-2, using traffic traces corresponding to a pair of hours of traffic, in order to perform a capacity assessment.

Thank you all dear distinguished researchers
