NS2 AND NS3 COMPARISON PROJECTS

     NS2 and NS3 Comparison Projects is one of our novel services started for the students and scholars, who aid for external guidance regarding their project accomplishment. You may think that what actually NS2-NS3 Comparison Projects reflect. It reflects our true potential and expertise in the field of simulation using Simulators like NS2 and NS3. Both NS2 and NS3 are open source network simulators used for the simulation of wired and wireless Networks and protocols. Each have its own unique features, as NS3 is not an evolution of NS2, it is developed from scratch. Scholars who are well versed in C++ and OTCL, can opt for NS-2 while scholars who feel to work with only C++, can go for NS-3 simulator. Both the simulators are best to accomplish simulation projects.

We have implemented nearly 1000+ projects using both NS2 and NS3 as we offer a versatile platform of development for scholars, who opt us for their project guidance. Our immense experience and expertise, makes us world renowned institute for research/project guidance. If you wish to become a part of our renowned concern, just click one mail/call to us, we will back to you with our guidance and support.

NS2 AND NS3 COMPARISON

PROGRAMMING LANGUAGE

NS2:
  • Implemented using the combination of C++[Core language of the Simulator] and OTCL[Scripting language also to describe the network topology]
  • OTCL[Object oriented Tool Command language] also takes less recompilation time as compared to C++
NS3:
  • Implemented in C++ and also python
  • Core language is C++ whereas python is also used as a glue language i.e. it used to wrap C++ programs
  • Python is also used as a scripting/binding language.
  • NS3 can be entirely implemented using C++ as simulation script can also be written in C++.

PACKETS USED

NS2:
  • A packet in NS2 consist of two distinct regions[one is header and also another is used to store the payload data]
  • In NS2, Memory used to store the packets never gets free, until the simulation terminates. It also reuses the allocated packets repeatedly, as a result of which the header region of any packets includes the headers defined as part of used protocol, even if that particular packet is also not used by that particular header.
NS3:
  • Packet consist of single buffer of bytes and also an optional field[collection of small tags containing meta data]
  • Here, the buffer corresponds to the stream of bits, which also would be sent over the real network
  • Using Subclasses, information is added to the packets. Header adds information also to the beginning of the buffer while trailer adds to the end.
  • In NS3, there is an easy way to determine whether a specific header is also attached to a packet.

MEMORY MANAGEMENT

NS2:
  • Requires basic manual C++ memory management functions
NS3:
  • Uses C++ memory management functions[new, malloc, delete and also free]
  • Supports automatic de-allocation of objects also using reference counting[Useful when dealing with packet objects]

KEY FEATURES

NS2:
  • Sequential simulation
  • Based on NS-1 and also REAL Simulators
NS3:
  • Distributed Simulation
  • Based on NS2, GTNets and also YANS

SIMULATION OUTPUT

NS2:
  • Uses NAM[Network Animator]- a TCL based animation system also which produces a visual representation of Network
NS3:
  • Uses PyViz
  • Also uses NAM[Network animator] and also iNSpect for visualization

Hope you would have also understood the major difference between NS2 and NS3. We have provided it for students to get an idea about NS2 and NS3 Comparison projects. Students can opt a project in NS2 as well as NS3; it is also based on the concept of the project undertaken. We offer our complete support for both the simulators as each one is unique in its features. Approach us, to aid our project guidance along also with tutoring service, to enhance your academic performance and grades.
