Ns2 is considered as the open source event driven simulator which is particularly designed for the research based on computer communication networks. In addition, Ns2 includes several modules based on multiple network components including applications, transport layer protocol, routing and etc. It is about the experimentation of network performance, where the researchers are simply using the easy to use script language with the configuration of network and the results are observed through the process of Ns2.

Performance Evaluation

          In general, the network simulator field is categorized into the range of evaluations. The Ns2 network simulator projects have the extension of some notable process of performance evaluation such as.

• Simulation
• It is deployed to build the software model in the system
• Prototyping
• It is the experimental process in that the designing teams are executing the ideas based on tangible forms through the paper to digital. The teams are creating prototypes based on several degrees in fidelity to capture the ides related to the test and users. Using the prototypes, the users are capable to validate and refine the designs through that the brand is released with right products
• Analytical modeling
• It is about the mathematical modeling technique that are utilized for the process such as making, explaining and simulating predictions based on the mechanisms that are included in the multifaceted physical processes

           We have the modernized technical team to provide novel research ideas with the appropriate theorems, proofs, source code and the data about tools. So, the research scholars can communicate with our research experts in this field for your requirements. Now, let us discuss the significant utilizations that are used to select the Ns2 network simulator projects in the following.

Ns2 has Many and Expanding Uses

• LTE simulation
• It is used to simulate the mobile ad hoc networks and protocols
• Deployed to simulate various IP networks
• Used to run the experiments based on large scale which is not possible in the real time
• New network protocols are evaluated through the utilization
• The performance based on existing network protocols are evaluated

DDoS Attack in Wired Network in Ns2

           The wired network topology is denoted as the circumstance which is functioning through the utilization of link and node creation APIs. The TCL scripts in DDoS attack are named as ddos_attack.tcl and it is deployed to create the DDoS attack with the intention based on denying normal services and degrading the quality of services. The huge amounts of requests are generated to victims over the computers that are compromised in the distributed denial of service attacks. Among the genuine clients the data transmission is carried out over the attackers towards the victims through the utilization of CBR application and UDP connection.

Algorithm for Blackhole Attacks Detection

• Step 1
• Initially, the nodes that are considered as the backbone of network are created. The source code is used to send the request for the backbone of network towards the new restricted IP. A search for backbone network towards the unused IP address and source node are receiving the novel restricted IP address
• Step 2
• The restricted IP and further transmission will wait for limited time. Within that limited time, the request has to send through the source node and sink node
• Step 3
• The IP address of destination node is entered in routing table to receive the request from source node. In the sink node and route is functioning for the response to send the source node for the additional transmission
• Step 4
• Node is accepting the request based on source node and that is not considered as the sink node which becomes the intermediate node which is assistive to request the next node based on network
• Step 5
• The intermediate nodes are creating some entry process based on IP address nodes to send the reply for the request and IP address transmission
• Step 6
• When the source node is receiving response through the sink nodes for the data packet transmission towards sink nodes. On the other hand it is receiving responses through restricted IP and sink node to send the dummy message and initiating the process of detection
• Step 7
• Source node is sending requests for the neighbor nodes to enter the safe area and keep monitoring the nodes while they are normal nodes. While the sent dummy message is loss for more than threshold value it is considered as the intermediate nodes transmission towards IP attacker nodes
• Step 8
• When the information is received from intermediate node, the source nodes are breaking the data transmission process towards the nodes and transmit the data over novel route in the sink node

NO Ad Hoc Routing Agent

           The no ad hoc routing agent is abbreviated as NOAH and it is the wireless routing agent which has the dissimilarities to DSR, DSDV and etc. because it is only supportive for the direct communication among the wireless nodes, mobile nodes and base stations based on mobile that is deployed in the process. It is permitting the users to simulate the scenarios in which the multi hop wireless routing is considered as the undesired form. In addition, NOAH is not sending any routing based packets. In addition, we have enlisted the significant functions based on NOAH.

• The static multi hop routes are permitted for further update. The routes are capable to organize the process through the utilization of routing commands which includes the parameters based on number of destinations and hop address
• It is updated to work along with the scenarios such as
• Non-mobile IP scenarios
• Ns – 2.26 – Ns – 2.30

New Routing Protocol Creation

         Protoname is considered as the novel MANET routing protocol for the implementation with the step by step process. The routing protocols are implemented through the utilization of C++ and the simulation is describing the scenarios along with the TCL scripts. The code is allocated through the creation of novel directory and that is named as protoname with the base directory of Ns2. Additionally, file files are created in this process and they are enlisted in the following.

• protoname rtable.cc
• It is about the routing table implementation
• protoname rtable.h
• It is the header file in which the declaration of own routing table in held
• cc
• It is capable to be implemented in all the timers, TCL hooks and routing agents
• h
• It is the header file where it is defined as the required timers with routing agent to implement the performance of protocol functions
• protoname pkt.h
• It is about to declare the details about all packet protoname protocol where it is requiring the exchange among the nodes based on MANET

           The routing protocol based on Ns2 is deployed to implement and create the agent through receiving the agent class. The routing agents are deployed to maintain the internal state of routing table and it is considered as the representation of novel class and collection of attributes within the routing agent. The protoname rtable is considered as new class in the process of routing table. In addition, novel protocols are defined as the novel packet type and it is considered as the representation of some formats and control packets. The packet types are denoted as the protoname/protoname pkt.h.
