NS2 Simulator: An Introduction
Networking , Technology & Science / September 14, 2017

Simulation Overview Simulation is widely-used in system modelling for applications ranging from engineering research, business analysis, manufacturing planning, and biological science experimentation. Networking study, implementation, testing and evaluation is not feasible without Network simulation. It is a technique where a code incorporates the behaviour of a network by calculating the interaction between the different network entities (hosts/packets, etc.) using mathematical modelling. Simulators are used for the development of new networking architectures, protocols or to modify the existing protocols in efficient environment. Network simulator provides benefits of time as well as cost saving while implementing and testing any wired or wireless network. Due to growth of communication networks and ever increasing networking speed, the role of efficient Network simulators in research field is important. A network simulator is a piece of software or hardware that predicts the behaviour of a network, without an actual network being present. A simulation is, more or less, a combination of art and science. That is, while the expertise in computer programming and the applied mathematical tools account for the science part, the very skill in analysis and conceptual model formulation usually represents the art portion. A simulation can be thought of as a flow process…
