Transformation and Analysis of Wire line Networks to Wireless Networks Using OPNET Simulator

Abstract

The telecom sector is undergoing rapid changes and with the emergence of a new technologies competition to provide a different range of services has increased. As now the customers are more demanding and they need to get the services at a very fast rate and in minimum time. A race to get high speed data is becoming very high. So in order to survive it is very much necessary to replace the old wire line systems with new wireless networks and the transformation should be such that we can get best network quality at optimum cost. Till now, the most important communications platform in most of the countries is the public switched telecommunication network (PSTN), which provides access to all households and buildings across most of the countries. This paper gives a description of the wire line and wireless networks, its basics, its transformation need for transformation towards wireless networks and analysis of wireless networks using OPNET Simulator. It will also describe why VOIP is a better technology over PSTN, its advantages over PSTN. To get the optimum performance of wireless networks it is necessary that its QOS parameters should be within the acceptable range and for that analysis and simulations of networks is needed. Here OPNET simulator is discussed taking wide different areas of applications and the OPNET tool is compared with the other available simulators in order to prove the versatility of application of the simulation tool. Finally the paper is concluded showing its edge over other simulator giving valuable directions for its employment in various other applications.
