How to add a black hole attack in AODV protocol in ns2.

https://www.nsnam.com 

Black hole is the basic attack in a network, here we are going mitigate this attack in ns2.

Trust value, based on the trust value, if the value is less, then we can make it as an attacker node.

High trust, medium trust and low trust (integer)

Trusted or not (boolean)

To make a node attacker node (preferanly a black hole attack, how to do that?)

AODV protocol as it is easy to implement in ns2.


Step 1: Declare the attacker variable
We will two files aodv.h and aodv.cc files 
in aodv.h file, 
create a variable name as given below in the protected scope

bool attacker;

Step 2: initialise the attacker variable as false.
In aodv.cc file, initialise the attacker to be false inside the constructor.


Step 3: if a node is a blackhole, what happens to attacker value
in the command() function of aodv.cc file inside the block 
if(argc==2), include the following lines

if(strncasecmp(argv[1], "blackhole") == 0) {
attacker=true;
      return TCL_OK;
    }

Step 4: If the node is an attacker node, what it will do?
if(attacker==true)
{
printf("Packets dropped by node number %d is %d \n",index,t_count++);
drop(p,DROP_RTR_ROUTE_LOOP);
}


Open the terminal and go to ~ns-2.35/ and execute the command 

$] make 

If no errors, in the above logic your compilation is successful.

Step 5: Run the TCL file with AODV protocol, with Attacker code and without attacker code and compare both the results.

$] ns AODV.tcl

You can compare the node with attacker and without attacker
Here is the comparison for an attacker node (node number 5)

When node 5 was an Attacker node, these are the results
Number of generated packets: 4
Number of sent packets: 2
Number of forwarded packets: 2
Number of received packets: 22
Number of dropped packets: 16
Number of lost packets: 0
Number of sent bytes: 204
Number of forwarded bytes: 88
Number of received bytes: 1000
Number of dropped bytes: 472
Minimal packet size: 40
Maximal packet size: 102
Average packet size: 49.6923

When node 5 was a good node, here is the result

Number of generated packets: 446
Number of sent packets: 446
Number of forwarded packets: 443
Number of received packets: 465
Number of dropped packets: 0
Number of lost packets: 0
Number of sent bytes: 373736
Number of forwarded bytes: 347724
Number of received bytes: 348764
Number of dropped bytes: 0
Minimal packet size: 32
Maximal packet size: 1598
Average packet size: 790.4165

  7. Sir, respectfully, I hope you could at least reply comments because some of us actually followed the exact same thing as you did, but the output wasn't the same.

  8. Sir, Can i apply the same method to simulate Blackhole attack in Proactive routing protocols like DSDV and FSR.
