[ns] How to use Error Models with Wireless channels ?

Dear P.Navaratnam, I have the same problem , Have you solved itplease let me know if you overcome it. According to me: I select the shadowing model as propagation model for wireless link. In this model you can specify the loss ratio ( just read chapter 18 in ns-doc.pdf file) if you solve

[ns] How to start the node at appointed time.....

Assuming I have three wireless node, I want to set Node0 power ON at 10s (in other words, deploying in network) Node1 power ON at 20s Node2 power ON at 30s But I've tried it in TCL code and its seems that it can't support a = function like this. $ns_ at 10.0 set node_(0) [$ns_ node] $ns_ at

Re: [ns] how to get the rooting table????

Hi Amel, To get the routing table on each node 1. Find out which is the routing algorithm that you are using in your simulation. 2. In the code corresponding to the implementation of that routing algorithm, find out where is the routing table structure defined and what is the structure. 3.
