What are the four files on the NS2 simulator?

What are the four files on the NS2 simulator?

Ns2 uses a . tcl file to view the simulation of a network….The objective

  • This network consists of 4 nodes (n0, n1, n2, n3).
  • The duplex links between n0 and n2, and n1 and n2 have 2 Mbps of bandwidth and 10 ms of delay.
  • Each node uses a DropTail queue that has a maximum size of 10.

What is NS2 in wireless network?

Ns-2 is a widely used tool to simulate of networks. Network simulator is a part of software that predicates the performance of a network without a real network being there. NS2 is a vital simulation tool for networks. and support popular network protocols, offering simulation results for wireless networks.

What are the advantages of NS2?

Advantages of Ns2 simulation Ns2 simulation is cheaper sometimes. Sometimes it finds bugs (in design) in an advanced manner. Generality: over analytic/numerical techniques, it gives more generality. Detail: At an arbitrary level, system details also can be simulated.

What are advantages of simulation?


  • It can avoid danger and loss of life.
  • Conditions can be varied and outcomes investigated.
  • Critical situations can be investigated without risk.
  • It is cost effective.
  • Simulations can be sped up so behaviour can be studied easily over a long period of time.

Which type of simulator NS2 belongs to?

NS is licensed for use under version 2 of the GNU (General Public License) and is popularly known as NS2. It is an object-oriented, discrete event-driven simulator written in C++ and Otcl/Tcl.

What is the 3rd column in the contents of trace file?

The last three columns list the possible flags, types, and values for the event under the Flag, Type, and Value headings.

Can we run NS2 online?

NS2 is a open source software. It can be downloaded from Internet and installed.

What are the features of NS2?

2. Features of NS2

  • It is a discrete event simulator for networking research.
  • It provides substantial support to simulate bunch of protocols like TCP, FTP, UDP, https and DSR.
  • It simulates wired and wireless network.
  • It is primarily Unix based.
  • Uses TCL as its scripting language.
  • Otcl: Object oriented support.

Why are simulation games a great way to help students learn?

Simulations and games have great potential to improve science learning in elementary, secondary, and undergraduate science classrooms. They can individualize learning to match the pace, interests, and capabilities of each particular student and contextualize learning in engaging virtual environments.

Why do we need network simulator?

Network simulation offers an efficient, cost-effective way to assess how the network will behave under different operating conditions. Simulation results can be analyzed to assess network performance, identify potential problems, understand the root cause, and resolve the issues prior to deployment.
