[ns] how to know the number of node at the neighbor of a node

[siad lamri]

hi ns users;
   
  i'm using ns2 version 2.29 to simulate a multihope Ad hoc network (802.11). In my simulation i need to know, for a given node, the number of nodes in his neighbor. So i don't  know if it is implemened in ns2; and if it exists what is the command and the syntax to do this.
   
  please it blocks me to continue my work.
   
  kindly
