Abstract

In telecommunication, traditionally telephone networks uses basic concept called circuit switching for doing communication between sender and receiver such as Public Switched Telephone Network (PSTN). Nowadays this type of switching is being replaced by packet switching where the transmission of data is done in packets and networks based on this are referred to as connectionless networks. Voice over Internet Protocol (VOIP) is an emerging technology which is based on packet switching and is going to be used for the transmission of voice and multimedia over the Internet Protocol (IP) based network, especially the Internet. Another is WiMAX Technology which is also an upcoming wireless technology that provides us high speed mobile data and telecommunication services. These technologies are in use to replace the traditional telephone networks i.e., Public Switched Telephone Network (PSTN). In this paper performance of such networks which uses VOIP technology is investigated and for which OPNET 14.5 Simulator is chosen as the platform. OPNET Simulator provides simulated real-life environment, in order to study the performance of the next generation networks. The parameters used to evaluate the performance of the networks are jitter and end to end delay. Finally based on the simulations best VOIP codec is also found out.
