Performance comparison of VoIP over wireless ad hoc networks using different routing protocols and queuing techniques

Abstract

This paper describes performance evaluation of VoIP over wireless ad hoc networks using OPNET tool. The simulation study is completed by running VoIP application in different network scenarios with different routing protocols; namely: AODV, TORA and DSR and with different queuing techniques: FIFO, PQ and WFQ. The following performance parameters: the delay jitter, packet end-to-end delay, wireless LAN delay, and number of packets sent/received are used to compare the efficiency of different scenarios.
