OPNET: A NEW PARADIGM FOR SIMULATION OF ADVANCED COMMUNICATION SYSTEMS

Various simulation tools play very important role in today’s engineering & technological projects and in research works also. Using these tools researchers can realize, estimate & evaluate the performance of any system which is hard to implement in real time. In this paper, we have employed OPNET as a simulating tool to study different aspects of Wired and Wireless Communication technology. This work helps to create a prototype of any practical Networking project and evaluate the parameters of the communicating devices so that the Quality of Service (QoS) of the network is maintained. Consequently practical job becomes efficient, cost effective, unstrained and clean when the various parameters obtained from the simulation are actually used in the real time projects. Since it is impossible to do justice to this large body of research in this short survey, we discuss from a wide spectrum and level of work, such as. Since it is a large spectrum of research, we have confined ourselves to study how delay, load, Page Response Time, etc parameters vary from node to node in different environments, in this paper
