Tcl 如何在ns2中查找邻居列表
我想找到传感器网络中的邻居节点列表。如果有人能为我提供一个tcl脚本示例,那将是非常有帮助的。谢谢Tcl 如何在ns2中查找邻居列表,tcl,ns2,Tcl,Ns2,我想找到传感器网络中的邻居节点列表。如果有人能为我提供一个tcl脚本示例,那将是非常有帮助的。谢谢#邻居节点计算 # neighbor node calculation set nbr [open Neighbor w] puts $nbr "\t\t\t\t\tNeighbor Detail" puts $nbr "\t~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~" puts $nbr "\tNode\t\tNb node\t\tNode-Xpos\tNode-Ypos

set a 0
set nbr [open Neighbor a]
set x1 [expr int([$n1 set X_])]
set y1 [expr int([$n1 set Y_])]
set x2 [expr int([$n2 set X_])]
set y2 [expr int([$n2 set Y_])]
set d [expr int(sqrt(pow(($x2-$x1),2)+pow(($y2-$y1),2)))]
if {$d<300} {

}
}
close $nbr
}
U can use above function to print neighbor node's of all nodes in ns2.
设置nbr[开放邻居w]
放入$nbr“\t\t\t\t\t详细信息”
将$nbr“\t~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~”
放置$nbr“\tNode\t\tNb node\t\tNode Xpos\tNode Ypos\tNb Xpos\t\tNb Ypos\t\t立场(d)”
将$nbr“\t~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~”
收盘价$nbr
过程距离{n1 n2 nd1 nd2}{
全局c n bnd src dst j0 j1
设置一个0
设置nbr[开放邻居a]
集合x1[expr int([$n1集合X_uz])]
集合y1[expr int([$n1集合Y])]
集合x2[expr int([$n2集合X_U4;]])]
集合y2[expr int([$n2集合Y])]
集合d[expr int(sqrt(pow($x2-$x1),2)+pow($y2-$y1),2))]
如果{$d到目前为止您尝试过做什么?(Stack Overflow鼓励人们在寻求帮助之前自己尝试。)
for {set i 0} {$i <$val(nn)} {incr i} {
for {set j 0} {$j <$val(nn)} {incr j} {
$ns at 10.002 "distance $n($i) $n($j) $i $j"
}
}
here val(nn) denotes number of nodes.
