We offer * MS Network simulator projects* which deal with various network technologies and protocols.Network referred as set of computer systems and various computer hardware devices linked by a communication channel. Among number of users, communication channel are used to ensure a resource sharing. We support and develop various network simulators such as NS2, NS3, Opnet, Omnet and Netsim based projects for MS students. Discipline of computer and information technology MS students carry their projects in networking.

**Algorithms used for MS Projects:**

Network projects are developed by us with various algorithms such as markov chain, Differential evolution algorithm and hop by hop message authentication derived from Science Direct Papers.

**Markov Chain Algorithm:**

We implement markov chain for clustering process in networking. It composed of present state, future and past state. At every process, it change state based on probability distribution simple graph with undirected graph which every non zero weight equal to 1. String rewriting is introduced by markov chain algorithm.

**Differential Evolution Algorithm:**

We developed differential evolution algorithm which is a type of genetic algorithm and it is implemented to solve many engineering problems. We deploy a

stochastic optimization method to minimize a function with incorporating constraints.

**Steps of DE Algorithm:**

We follow various steps for DE algorithm for academic projects are:

- Initialization.
- Evaluation.
- Repeat.
- Recombination.
- Selection.
- Termination.

**Advantages of DE Algorithm:**

The following advantages are attained by us in the implementation of DE algorithm are:

- Ease to use.
- Being simple.
- Adaptable to all networks.
- Nonlinear constraints.
- Fast convergence.

**Hop By Hop Message Authentication:**

To enhance a security concept in our project we provide message authentication for unauthorized access and corrupted message. Hop by hop message authentication verify authorized user in every network node. In routing path every forwarder checks authenticity and message integrity.

**Objectives of Authentication in Network:**

Following objectives are attained by our team in network are:

**Message Integrity:**

Receivers verify that whether message is changed by route attackers.

**Identify and Location Privacy:**

Attacker determines sender ID and location by analyzing a message contents.

**Efficiency:**

Various overhead such as computation and communication are reduced.

**Message Authentication:**

- Receiver verifies that whether message is received from proper claimed node.
- Security in network is enhanced by authentication process involved in hop and multihop communications.

Using a network simulator we proposed more than 110+ projects with various algorithms
