如何在NS2中查找邻居列表 [英] How to find neighbor list in ns2

问题描述

我想在传感器网络中查找邻居节点列表。如果有人为我提供示例Tcl脚本，那将是非常有帮助的。谢谢

推荐答案

# neighbor node calculation

set nbr [open Neighbor w]

puts $nbr "					Neighbor Detail"

puts $nbr "	~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"

puts $nbr "	Node		Nb node		Node-Xpos	Node-Ypos	Nb-Xpos		Nb-Ypos		Distance(d)"

puts $nbr "	~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"

close $nbr

proc distance { n1 n2 nd1 nd2} {

  global c n bnd src dst j0 j1 

  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} {

    if {$nd2!=$nd1} {

      puts $nbr "	$nd1		$nd2		$x1		$y1		$x2		$y2		$d"

    }
    }



  close $nbr
}



U can use above function to print neighbor node's of all nodes in ns2.

调用"Distance"函数打印邻居列表 例如，

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.
