I guess in order to black list a node in a network, you first have to
declare malicious nodes in your network and ask them to perform a task (
like dropping of packets or generating and broadcasting those packets with
a Frequency parameter set to a small interval of time ). So what you have
to do is to define a variable of type bool in the
aodv.h file where you are defining your routing agent and then in the
aodv.cc , in the constructor initialize that bool variable as false.
Now i guess you have to insert an if statement in the int AODC :: comand ()
function for strcmp of an arg which you will pass from your tcl script .
Let say in your tcl script the malacious node you define passes an arg as
"bad node" etc .
if the comparison turns true then in a AODV, use a timer for this node (
take an example from broadcast timer etc) which can call a function to
boradcast the packets more frequently .
use if statements when receiving a packet from malicious node. or put a
limit of getting no of packets from this node. you can #define it after
header files in aodv.h.
I hope this lil knowledge can help you a bit .
