hello , your welcome. Well for all your questions i have one answer. Run a tcl script file that generates a trace file . in that file, you will have all the information as far as my knowledge is soncerned about originator of the RREQ packet. so there is no need for a counter. The node id descibes whether ot not its the originator of the packet or not. for the malicious node , as i said earlier , set a frequency of sending packets bu defining a max limit . Once all other nodes note that they are receving unnecessarily no of packets either discard or drop these packets by identifying the node id of such nodes .
