Network Simulator Master Thesis in Iraq:

  Network simulator Master Thesis in Iraq offer extremely structured thesis for your marvelous cerebral research with our creative and positive thoughts. NS2 is an open source and event driven and packet level simulation tool to simulate wide array of networking protocols and networks (local and satellite). Ns2 is coded using two languages, such as C++ for packet processing (fast execution, full control over execution to make simulator scalable) and OTcl for control (network configuration, simulation setup, infrequent actions). It is significantly support for simulation of protocols (TCP, RTP, HTTP, and SRM, Routing protocols namely OLSR, DSDV, AODV and DSR) which is mainly focused on networking based research. Now, we discuss about major Ns2 characteristics, communication entities, few simulation parameters, Ns2 programming development step and scripting structure.

Ns2 Characteristics:

  • Real-time Implementation
  • Plumbing makes NS2 as a powerful tool
  • Time synchronization
  • Event Scheduler
  • Extensibility
  • Cost Effective
  • Scalability
  • Object Oriented
  • Discrete event Simulation

Major communication Entities in NS2:

Classifiers:

  -The role of nodes is examined by received packets (source and destination address). According to contention losses, node sends packets on its outgoing interfaces. It is performed by an object (Classifier). There different classifiers are classified.

  • Address Classifier
  • Port Classifier
  • Multicast classifier
  • Hash Classifier
  • Multipath Classifier

Link:

   -Link is used to connect node to each other and it is declared by diverse of parameters namely bandwidth, lifetime of each packets, every points etc.

Agents:

  -Agent represent endpoints where packets in network layer (constructed and consumed). It provides destination address, its function is to create/ generate packets and interface to application class. The agents are defined by four types.

  • TCP agent (Emitting TCP traffic)
  • UDP agent (Emitting UDP traffic)
  • TCP Sink agent (Receipt of TCP traffic)
  • NULL agent (Receiving UDP packets)

Foremost Simulation Parameters:

  • Numerous of nodes
  • Network Topologies
  • Link Utilization
  • Queue Mechanism
  • Real traffic data (saved in text (.txt) file)
  • Total time of real captured

Major steps in NS2 programming:

Creation of Event Scheduler

  • Creating Event schedule
  • Schedule Events
  • Start scheduler

Open Tracing Files

  • Trace packets on all links
  • Turn on Tracing on exact links

Creating Network/ Topology

  • Create Nodes (Compute routes and setup routing)
  • Linking and Queuing (Bandwidth, delay and queue type)
  • Creating Transport Connections (Agents)
  • Creating Traffic (Applications)

 -UDP & UDP (Create agents, attach to nodes and set up connection)

 -TCP – TCP sink

 -TCP (Friendly link less Protocols)

  –TFRC – TFRC sink

  –RAP: Rate Adaptation Protocol (Rate based AIMD with slow start)

  –TCP friendly RCP (Rate Control Protocol) based on TCP through equation

  • Creation of Traffic Applications:

 -Use App (Top of agent)

   –On top of UDP(CBR)

  –On top of TCP (FTP)

 -Start and stop app

 -FTP (New Application/ FTP)

 -Telnet (New Application/ Telnet)

 -Web

 -Traffic Generator

Standardized Scripting Structure:

Set ns (New simulator)

  • # [Turn on tracing]
  • # Topology Creation
  • # Setup link dynamics and packet losses
  • # Create Routing Agents
  • # Create Multicast Group
  • # Create Protocol Agents
  • # Create Application and Setup Traffic Resource
  • # Post Processing
  • # Start Simulation
