Multicast Performance Comparison of SMF and ODMRP Using the CONFINE Testbed

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. Then, we do real-world experiments with an actual IEEE 802.11 ad-hoc test bed in order to compare the results and increase the overall credibility of our analysis. The comparison highlights differences in the performance of ODMRP and SMF, both in the real-world measurements and the emulation-based results. Our results show, that the scoped flooding approach of ODMRP might increase the applicability of multicast routing in community networks.
