In this paper, we propose virtual direction multicast (VDM) for video multicast applications on peer-to-peer overlay networks. It locates the end hosts relative to each other based on a virtualized orientation scheme using real-time measurements. It builds multicast tree by connecting the nodes, which are estimated to be in the same virtual direction. By using the concept of directionality, we target to use minimal resources in the underlying network while satisfying users' quality expectations. We compare VDMagainst host multicast tree protocol.We simulated the protocol in a network simulator and implemented in PlanetLab. Results both fromsimulation and PlanetLab implementation show that our proposed technique exhibits good performance in terms of defined metrics.
