Dear all Thanks your response, I try the code you writed, but it also can't work.... the trace file is all empty, and nothing to run... I tried another way set node_(0) [$ns_ node] $ns_ at 20.0 [set node_(1) [$ns_ node]]
there are something in trace file, but it stop in 19.xxx sec(my stop time is 300sec...) so...it seems has some troubles in the way....... I really don't know why~~~ ------------------------------------------------------ Subject: Re: [ns] How to start the node at appointed time.....
