Definition of Network Simulator:  Network Simulators are useful to simulate the nodes in the network for packet transmission. Using a network simulator, we can get more results in a smaller response time. Dynamic configuration of IPv6 and IPv4 is benefited from network simulator at the starting time of network agents. “This article contains the list of network simulators which are widely used in this current technology. Also, this is going to give a deep knowledge for some network simulators such as QualNet, LENA-LENA, PeerSim, LTE-Sim, and OneSim.”

PeerSim Network Simulator

           This Simulator gives support for dynamicity and achieves high scalability of the network. The structure of this simulator is written by java and this simulator contains two types of simulation engines. That is an event-driven simulation engine and a cycle-based simulation engine.

• The simulation engines are supported by
  • Flexible configuration mechanism
  • Pluggable, Simple and extendable components

The main functionality of a cycle-based engine is to eliminate the transport layer protocol details from the stack of communication protocols, useful for making a simple assumption and increasing scalability. To consider, an event-driven engine supports the transport layer simulation and is more realistic with less efficient.
