==Network simulator==

A '''network simulator''' is a [[software]] program that can predict the performance of a computer network or a wireless communication network. Since communication networks have become tooltoo complex for traditional analytical methods to provide an accurate understanding of system behavior, network simulators are used. In simulators, the computer network is modeled with devices, links, applications, etc., and the network performance is reported. Simulators come with support for the most popular technologies and networks in use today such as [[5G]], [[Internet of Things]] (IoT), [[Wireless LAN]]s, [[mobile ad hoc network]]s, [[wireless sensor network]]s, [[vehicular ad hoc network]]s, [[Cognitive Radio Networks|cognitive radio networks]], [[LTE (telecommunication)|LTE]]

==List of network simulators==

There are both free/open-source and proprietary network simulators available. Examples of freenotable open source network simulators / emulators include:

<!-- Only add simulators that have a wp article, and are mentioned in many research papers. Search at http://scholar.google.com. Do not add external links here. -->

* [[ns (simulator)|ns Simulator]]

* [[GloMoSim]]

* [[SimGrid]]

* [https://tetcos.com/download.html NetSim Lite]

There are also some notable commercial network simulators.

Line 32 ⟶ 30:

Network simulators provide a cost-effective method for

* 5G, 6G, NTN coverage, capacity, throughput and latency analysis

* Network R & D (More than 70% of all Network [[Academic paper|Research paper]] reference a network simulator)

* Defense applications such as [[UHF]]/[[VHF]]/L-Band Radio based [[MANET]] Radios, Dynamic TDMA MAC, PHY Waveforms etc.
