[ns] limiting the neighboring radius in NS2.33:please help

2009-01-29 Thread Nadine Chen

Hi all,
As you know, we can detect neighboring nodes, by sending and
receiving hello messages like what is done in AODV example.But when I did
this, I noticed that each node has a very large number of neighbors, so I want 
to limit this number by reducing the neighboring radius, but I didn't know 
where can I modify it?
Please , if any one has an idea to limit automatically this radius, or any 
other method to reduce the number of neighbours tell me how ?
Thank you very much for your help

Hi Nadine,

One way to reduce the number of neighbors is to reduce the average node
density. For example, you have a network of 100 nodes, then you can control
the number of nodes, let's say each node can have 10 neighbors or each node
can have 20 neighbors. To achieve this, you can vary the grid size and
random placement of nodes in the grid.

Second this is that, have you declared the node location in your tcl script
or load any coordinate file for the nodes? If you won't do this, ns2 will
consider that each and every node is the neighbor of each other. So,
consider this also.
