Protocols simulation and performance analysis in wireless network based on NS2

A four-node wireless network model is designed based on NS2 simulation platform software. The network performance, such as System delay, Packet loss rate, Throughput and other key indicators are simulated in this paper. By running of TCP and UDP protocols, we make the analysis and evaluation to network performance from different aspects, and then, associated parameters were compared graphically with gnuplot tools. Simulation results and conclusions have a positive referenced value for the design of wireless network topology and the configuration of network elements.
