Mobility-aware Rendezvous Point for mobile multicast sources
Résumé
The Internet research community has done a great effort to support mobile receivers in multicast session, but less interest was given to the problem of mobile sources. In fact, building source-specific tree with mobile sources is challenging. Depending on the nature of the mobility of the multicast source, several problems emerge such as the handover transparency, the multicast service interruption, and the reconstruction of the multicast delivery tree after each handover. In this work, we develop a new solution to make multicast source mobility transparent. Our solution introduces a new entity called Mobility-aware Rendezvous Point (MRP) in order to handle the mobility of a multicast source in both intra-domain and inter-domain multicasting. Our solution uses a smooth handover technique between MRP peers and interoperates efficiently with existing multicast routing protocols.
