Network Simulator Linux

NS-3 is a free software simulation platform which aims at network technology and whose source code is open. NS-3 contains an abundance of modules, almost relating to all the aspects of network technology. It’s an open source software development

Network Simulator Linux

• Most often the network simulations are done using the Linux.
• The ns3 is also developed by the Linux/Ubuntu or windows.
• If we want to develop ns3 programs in windows means we have to use the additional supporting software is that cygwin.
• Cygwin is also first of all creating the Linux environment in windows then only we can execute the programs.
• When compared with ns2, ns3 is simple and easy to learn.
• Whatever it is we want to install and execute ns3 programs means we need Linux platforms.

• From that ns3, we can simulate any kind of networks and gather the network performance.
• The networks are,
• Wired network
• Wireless network

Green computing.

• The network parameters are,

Packet delivery ratio.
