Satellite - Link delay

[Martin Koyabe <koyabe@erg.abdn.ac.uk>]

Hi All,

Are there any of you who have similated satellite delays and bit-errors using NS ? I am 
interested in simulation, errors, looses (due to bit-errors) and significant asymmetrics 
for large users in a one-hop scenario for a geo-satellite case !!


I have the following topology:-

create network topology like this:
                            (3) Receiver 1
                            /
                           /
        Source (0)--------1 Satellite
                           \
                            \
                            (2) Receiver 2
                            
                            

Would the a code like this make sense:-

$ns simplex-link $nodes_(0) $nodes_(1) 4Mb 125ms 
$ns simplex-link $nodes_(1) $nodes_(0) 1Mb 125ms 
$ns simplex-link $nodes_(1) $nodes_(2) 4Mb 125ms 
$ns simplex-link $nodes_(1) $nodes_(3) 4Mb 125ms 
$ns simplex-link $nodes_(2) $nodes_(1) 1Mb 125ms 
$ns simplex-link $nodes_(3) $nodes_(1) 1Mb 125ms 


I'll appreciate any comments/suggestions/leads !!
