In this paper, we present preliminary results from a performance comparison between the two multicast routing protocols ODMRP and SMF. While SMF uses a proactive selection of forwarding nodes, ODMRP is a reactive approach to multicast routing. For the evaluation, we use an two-step approach. First, we perform emulation-based measurements in a virtualized test bed utilizing the ns-3 IEEE 802.11 model...
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...
A Mobile Ad-hoc Network (MANET) is a dynamic wireless network that can be formed without the need for any pre-existing infrastructure in which each node can act as a router. One of the major challenges of MANET is the design of vigorous routing algorithms that adapt to the frequent and randomly varying network topology. Numbers of routing protocols have been proposed and several of them have been...
