CODE NS2 PROJECTS

      Code Ns2 Projects offers you complete guidance and support to enlighten your project work with our effort. The soul of the project is its code, which makes it what it is. Everyone can code in Ns2, but what really matters is the final outcome. If your project output doesn’t show, what you mean, them how can you call it as your project? This is the major problem, many students face today. Code Ns2 Projects have come up as a solution for your all problems. We are here to offer you our complete support for your project code and implementation. You can also approach us through online and get code for any particular assignment topic or project. We will offer you our all round for the successful accomplishment of your project.

CODE NS2 PROJECTS

     Code Ns2 Projects, an amazing solution started in a positive hope to serve the various needs of budding students. We have versatile developers and experts, who can serve you with their talents and skills. To code in Ns2, the foremost important aspect is to know about the key factors of Ns2. Network topology, algorithms, routing protocols and attacks are the key factors, which plays major role in the implementation of a networking projects. Here, we have emphasized about networking attacks, to make you clear with one of the major aspect of networking project. We have listed all the major attacks in the network along with one sample code example for your better understanding about Ns2 code.

MAJOR NETWORK ATTACKS:

Wireless Sensor Network attacks:

  • Black hole attack
  • Sinkhole attack
  • Worm hole attack
  • Replay attack
  • De-synchronization attack
  • Sybil attack
  • Denial of service attack

Cognitive Radio Network attacks:

  • Primary User emulation attacks
  • Jamming attack:

               -Deceptive jammer

              -Constant jammer

             -Reactive jammer

             -Random jammer

  • Objective function attack
  • Selfish channel Negotiation
  • Lion attack
  • Control channel saturation DoS attack
  • Spectrum sensing data falsification

Mobile Ad hoc Network Attacks:

  • Sleep Deprivation attack
  • Byzantine attack
  • Flooding attack:

             -Route request flooding

            -Data flooding

  • Location Disclosure attack
  • Eavesdropping attack
  • Man-in-the middle attack

Sample NS2 code for black hole attack:

    Here, we have provided a sample code in Ns2 for black hole attack. In this code, initialization of black hole attack is done using TCL script while the node response with fake replies is written in C++.

Initializing Black hole attacks:

$ns at 0.0 "[$node1 set ragent_] blackhole1

$ns at 0.0 “[$node10 set ragent_] blackhole2”

$ns at 0.0 “[$node5 set ragent_] blackhole3”

Black hole attackers sending fake route replies:

if(rq->rq_dst == index)

{

#ifdef DEBUG

fprintf(stderr, "%d - %s: End-user Reply\n",

index, __FUNCTION__);

#endif

sqn = max(sqn, rq->rq_dst_seqno)+1;

if (seqno%2) seqno++;

sendReply(rq->rq_src,1,index,seqno,

MY_ROUTE_TIMEOUT,

rq->rq_timestamp);

Packet::free(p);

}

else if(Black hole Attacker==1000)

{

sqn = max(sqn, rq->rq_dst_seqno)+1;

if (sqn%2) sqn++;

sendReply(rq->rq_src,1rq->rq_dst_seqno,MY_ROUTE_TIMEOUT,rq-gt;rq_timestamp);

Packet::free(p);

}

 

     This is just a sample code for scholars to understand about an attack scenario in NS2. You may get a valuable point from our code example, I.e. to code in Ns2, TCL and C++ is a fundamental language. Our every content reflects something useful for you to learn. Get our support for any kind of code help regarding your project, assignments or research work. We can assure you that you will never regret to select us as your guiding hands.
