Analysis of VoIP traffic in WiMAX using NS2 simulator

Pranita D. Joshi, Smita Jangale

Abstract


Worldwide Interoperability for Microwave Access (WiMAX) is a wireless broadband technology, which supports point to multi-point (PMP) broadband wireless access. It is a fixed and mobile wireless access technology based on the IEEE 802.16 standards. Voice over Internet Protocol (VoIP), called Internet Protocol (IP) Telephony, Internet telephony or Digital Phone. It utilizes the IP network (Internet or intranets) for telephone conversations. In this paper we have analyzed the performance of different VoIP codecs over the best effort service flow for WiMAX network. The parameters considered for the evaluation of network are throughput, average delay & jitter. The simulation is done using network simulator 2 (NS2) by varying number of nodes and results are presented in graphical form.
