I want to simulate a two rows of 14 nodes in a wireless environment. The topology is:
(0)-(1)-(2)-(3)-(4)-(5)-(6) (7)-(8)-(9)-(10)-(11)-(12)-(13) And I set the nodes by: set $val(nn) 14 set half_nn [expr $val(nn)/2] for {set i 0} {$i<$val(nn)} {incr i} { if {$i<$half_nn} { set node_($i) [$ns node] $node_($i) set X_ [expr $i*250]----------------[1] $node_($i) set Y_ 200.0 $node_($i) set Z_ 0.0 } else { set node_($i) [$ns node] $node_($i) set X_ [expr ($i-7)*250] $node_($i) set Y_ 100.0 $node_($i) set Z_ 0.0 } } I've used these codes for only one line last time, it worked very well. But for the above codes, the data never be sent out except I modified the distance of [1] to 100. The trace file is empty... In the nam, I could see nothing. It said: node 0 did not defined... Is there anyone has idea about it? -- View this message in context: http://www.nabble.com/Strange-problem-in-ns2-tp21010233p21010233.html Sent from the ns-users mailing list archive at Nabble.com.
