Computer networks are being widely used in all fields of life, net-banking, military operations, disaster relief and social networking. As the usage of various computer networks grows so does the need to make these networks faster, efficient and secure greatly increase. Network simulators are used worldwide for education, commercial and Industrial purposes to simulate any part or entire network. There are numerous network simulators used day by day. Network simulators can be used to produce an approximation result of the network, which lays foundation for real time application or implementation. Researchers are not aware about facility and various network simulators available. The authors' paper gives an overview on different network simulators.
