I am simulating a hidden node scenario in ns2.35. I want to know how I can make a node hidden from the rest of the nodes in 802.11b network topology. I want to do it using the tcl script. Any help in this regard will be highly appreciated.
cheers
"Hidden Node" is a concept in wireless communication networks, and very common in Ad Hoc Networks.
1) If you are using any of the IEEE 802.11 standards, such as (b, g, e, n), u might want to start by building-up a broadcast scenario. This would require C++ programming and them .tcl scripting.
In this scenario, all involved nodes, lets say 10 nodes, will be broadcasting by sending periodic beacon messages. By putting the nodes far enough from each other in a sense that NOT all nodes can hear each other directly, you ll end up with a scenario of "Hidden Nodes".
2) Another simpler way would be to use the combination of UDP/CBR based on IEEE 802.11 communication, which can be configured in a .tcl. Where the concept nodes distance would be the same as described above.
There are many codes available on the internet, just Google them.
Good Luck...
