[ns] Adding obstacles in my network topology in NS2

[Imran khan]

hi,

I want to simulate an ad hoc network topology, where a vehicle travels on
the roads and communicates with other vehicles in its vicinity. I'm using
NS2 version 2.33 for this purpose.

I just want to know how can I add obstacles in my topology like, buildings,
trees etc. in NS2? I'm using a GRID like topology. I'm able to define roads
for vehicles to travel on, but there are open spaces (sort of), that enable
free propagation of wireless signal.

I want to see the effects of problems like hidden node etc. so for that I
need to incorporate some obstacles between my nodes like buildings, tree
etc.

any help regarding this will be highly appreciated.
