Performance Comparison of VoIP over Wireless Ad Hoc Networks Using Different Routing Protocols and Queuing Techniques
Budget: $30 – $250 USD
This paper describes the evaluation of VoIP performance in wireless ad hoc networks using the OPNET tool. A simulation study is completed running a 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 are used to compare the performance of different scenarios: delay jitter, end-to-end packet delay, wireless LAN delay, and number of packets sent/received.
This paper uses the OPNET simulation tool to analyze VoIP over an ad hoc network design model. OPNET is a discrete event system simulator that simulates the behavior of a system by modeling every event that occurs in the system and processing it with user-defined processes. OPNET allows designers to design and study the performance of communication protocols, devices, and applications with considerable flexibility. It provides a graphical editor interface for creating models of various network entities, from the physical layer module to application processes.
