A network simulator is software that predicts the behavior of a computer network. Since communication networks have become too 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 performance is analyzed. The simulators come with support for the most popular technologies and networks in use today such as wireless LANs, mobile Adhoc networks, wireless sensor networks, Adohoc Vehicular networks, Cognitive Radio networks, advanced LTE / LTE networks, Internet of Things (IOT ), etc. ...
In network and computer research, network simulation is a technique by which a software program models the behavior of a network, either by calculating the interaction between different network entities (routers, switches, nodes, access points, links, etc.). Most simulators use discrete event simulations - modeling systems in which state variables change at discrete points over time. The behavior of the network and the various applications and services it supports can be observed in a testing laboratory; several environment attributes can also be modified in a controlled manner to evaluate how protocols / networks will behave under different conditions.
