PERFORMANCE EVALUATION OF VIDEO CONFERENCING OVER AD HOC WIRELESS NETWORKS USING DIFFERENT ROUTING AND QUEUING TECHNIQUES

摘要

In this paper we present a comparative study using OPNET simulation tool for video conferencing over wireless ad hoc networks. The study performed using three different routing protocols (DSR, AODV, TORA) and three queuing techniques (FIFO, PQ, WFQ). Different scenarios exploiting a combination of routing and queuing are produced. A quality of service is measured by means of packet delay variation, packet end-to-end delay and network throughput.
