setdest 和cbrgen工具的使用，出现的错误

在路径 ~/ns-2.34/indep-utils/cmu-scen-gen/setdest下运行

./setdest -n 250 -p 0.0 -M 10.0 -t 10 -x 1500 -y 1500 > S250

在路径~/ns-2.34/indep-utils/cmu-scen-gen下运行

ns cbrgen.tcl -type tcp -nn 250  -seed 1.0 -mc 100 > T250
会得到s250和T250两个文件，把这两个文件拷到下面tcl文件的通路径下，运行tcl文件

$ns_ run

注意两点： setdest产生的文件用到了node_数组变量和god_变量 ,这里要在提出了文件中给出：

1. set ns_    [new Simulator]
2. set god_ [create-god $val(nn)]　　    ；#这里把create-god $val(nn)换成了左边这样，为了防止出现

   can't read "god_": no such variable
   while executing
   "$god_ set-dist 0 1 8"
   (file "S250" line 1004)

...这样的错误

哈哈哈哈好开心，自己解决的~~~~
