Mobile Network Simulation Research Based on NS

Simulation is playing the more and more important role in designing of modern telecommunication network.In order to evaluate the performance of network protocols in simulating environment,must analyze and process carefully the simulating results.The paper firstly introduces the hierarchical architecture,and how to install NS,then discusses its application in the process of mobile network simulation with a simulation example.Finally,analyze the mechanism of trace and discuss how to process the simulating results.The paper is quite useful for how to use NS and network protocol research.
