I remember I had problems with it too, and the problem was the Tcl package from slackware didn't have a few headers ns2 would need to build. Try building new tcl packages with the slackbuild from slackware 11.0 (the tcl packaging problem was fixed there). It might solve this particular compilation problem. > ./install: line179 : cd: ./tcl8.3.2/unix: nosuch file or > directory,/install: line 186: ./configure : no such file or > directory tcl8.3.2 configuration failed!

[ns] Nakagami propagation model
Hello, I'm trying to use the Nakagami propagation model in NS2 but I am unable to correctly set up its parameters to meet my requirements (I'd like to be able to test it with different transmission ranges, such as 500m and 1km). Can somebody help me with this? Thanks in advance, Sergio. -- Computer Networks and Security Laboratory (LARCES) State University of Ceara (UECE/Brazil)
[ns] 80211ext (?) - logic error at TXC handling ACKIndication
Hello, I'm getting those messages* while running simulations with any routing protocols. I am using 80211Ext MAC and PHY, with the tworayground propagation method. The parameters I am using are the ones listes in that IEEE802-11p.tcl file that comes with ns 2.34 witht the following two changes: Phy/WirelessPhyExt set Pt_ 0.281838 Phy/WirelessPhyExt set RXThresh_1.42681e-12 Is that something I should be worried about? thanks, sergio * logic error at TXC handling ACKIndication 4 logic error at TXC handling ACKIndication 0 -- Computer Networks and Security Laboratory (LARCES) State University of Ceara (UECE/Brazil)

try putting the opening brace in the same line, as in

[ns] How to check whether an attached agent/application is transmitting?
Hello all, # connection 1 set udp_(1) [new Agent/UDP] set null_(1) [new Agent/Null] $ns_ attach-agent $node_(0) $udp_(1) $ns_ attach-agent $node_(1) $null_(1) set cbr_(1) [new Application/Traffic/CBR] $cbr_(1) set packetSize_ 512 $cbr_(1) set interval_ 0.25 $cbr_(1) set random_ 1 $cbr_(1) attach-agent $udp_(1) $ns_ connect $udp_(1) $null_(1) $ns_ at 1.0 "$cbr_(1) start" $ns_ at 5.0 "$cbr_(1) stop" the above tcl snippet will set up a UDP/CBR connection between nodes 0 (sender) and 1 (receiver), from 1.0 to 5.0 seconds. How would I -- on node 0, through C++ --, access the attached UDP agent to check whether it is transmitting or not? thanks in advance for any pointers. sergio
Re: [ns] Is there any way to SHUTDOWN a MobileNode?
Hello,
have you tried calling "reset" for the node you want to turn off?
something like
# tell all nodes when the simulation ends
for { set i 0 } { $i < $opt(nn) } { incr i } {
$ns_ at $opt(stop).0 "$node_($i) reset";
}
att,
sergio
