Settting up selfish nodes on AODV protocol

[Shanen Leen]

Hi,

I want to use AODV protocol to simulate some selfish/malicious(Drop packets with some probability/drop all the packets) nodes in a MANET.

I have gone through this thread and came up with following. Source files are also attached.

--- aodv-routing-protocol.h

Added a boolean field IsMalicious along with getters and setters.

--- aodv-routing-protocol.cc

In RoutingProtocol::GetTypeId(void) method, I've added

.AddAttribute("IsMalicious", "Is the node malicious",

BooleanValue(false),

MakeBooleanAccessor(&RoutingProtocol::SetMaliciousEnable,

&RoutingProtocol::GetMaliciousEnable),

MakeBooleanChecker())

And at the end of RoutingProtocol::RouteInput(...) method,

       if (GetMaliciousEnable()) {

std::cout << "---Malcious Node: Packet dropped\n";

return false;

}

else {

        // Forwarding

        return Forwarding(p, header, ucb, ecb);

        }

I just wanna drop the packet if the node is malicious.

As the simulation script I've used the example "manet-routing-compare.cc" and tweaked it.

-Made AODV as the protocol by setting "m_protocol(2)" in the RoutingExperiment::RoutingExperiment() constructor.

In the script's RoutingExperiment::Run(..) method, I have 3 node containers(One for all nodes, one for malicious, one for good nodes).

Then I created 2 AodvHelpers. First one create good nodes. On the second helper I'm calling Set("IsMalicious", BooleanValue(true)).

Then on the "InternetStackHelper" I'm calling,

internet.SetRoutingHelper(aodv);

internet.Install(goodNodes);

internet.SetRoutingHelper(maliciousAodv);

internet.Install(malNodes);

After all I'm not getting the "---Malcious Node: Packet dropped" message. And there's no increase no. of packets dropped in the FlowMonitor output either.

Can someone help me to figure out the issue here.

Thanks!

I don't see any malicious node in your script:

 for (x = 0; x < nGoodNodes; x++) {
   goodNodes.Add(adhocNodes.Get(x));
 }

 for (; x < nWifis; x++) {
   goodNodes.Add(adhocNodes.Get(x));
 }

Thanks Tommaso. 

Now I get the expected behavior.

For anyone who will see this in future,

Just change "goodNodes" in the second loop to "malNodes".
