Network Simulation and Performance Analysis Based on NS2

The operation of network is invisible, and for the real-time understanding of the network efficiency, network simulate is a positive means. With NS2, the professional Network Simulation tool, the end-to-end network is simulated, and various performances of the network are tested, including propagation delay, jitter, packet-loss ratio and throughput etc. This paper presents the dynamic generation of the network model and the parameter of network capability, gives the principle and method of simulation based on NS2, and analyzes specifically the simulation results.
