MC-PIM-SM: Multicast routing protocol PIM-SM with Multiple Cores Shared tree for mobile IPv6 environment

Internet research community has proposed many different multicast routing protocols to support efficient multimedia application such as, IPTV, videoconferencing, group games. Nevertheless, the design of all these protocols does not take into account that group members may be mobile. Indeed, with the arrival of Mobile IPv6 by IETF providing mobile users with continuous access, group members in the network are very dynamic affecting on the quality of both routing protocol scheme and multicast tree used. The key idea of this work is to make the handover of multicast members transparent and avoid the reconstruction of the entire multicast-based tree, by using an architecture MC-PIM-SM based in PIM-SM multicast routing protocol with Multiple Cores Shared Multicast Tree to hide the mobility of mobile multicast members from the main multicast delivery tree. Simulation results show that good performance is achieved in terms of handoff latency, end-to-end delay, tree construction delay and others metrics.
