[ns] Selecting malicious nodes in AODV

2013-07-02 Thread Teklay Gebremichael Welegebrael
Hello all, I am currently analyzing the effect of RREQ flooding attack in AODV. I used the scripts (setdest and cbrgen.tcl) to generate the mobility and traffic files randomly. But I want none of the malicious nodes should participate in the source-destination pair. Is there any way (other

Dear ns-users, I am working on ns-2 simulation of AODV protocol. I just want to use the neighbor table to add some information. But the lookup function always returns FALSE in my case when i want to print the neighbors for a given node. I can see that there are neighbors from the trace file that

Dear All, I just tried to modify the C++ code of AODV such that one node tries to flood rreq to a destination that doesn't exist based on some information I got on the web. let me explain what I did. I added a class FloodTimer to aodv.h as follows. class FloodTimer : public Handler { public:

Hi Every one, I just tried to look my doubt in FAQs, and didn't find one that matches. I am Just working on a simulation analysis of rreq flooding attack in reactive protocols especially in AODV routing protocol. I need to change the AODV code to implement the flooding attack so that one of
