Design and Implementation of Light-Weight Mobile Multicast for Fast MIPv6
Source: Reed Elsevier
Mobile multicast is a research hotspot and can provide many applications. Some mobile multicast schemes have been proposed, but most of them introduce new entities and study construction algorithms of the dynamic multicast delivery structure which is heavyweight for wireless devices. In this paper, the authors propose a Light-weight Mobile Multicast (LMM) scheme for Fast Mobile IPv6 which reduces the redundant operational overhead by simplifying Multicast Listener Discovery (MLD) proxying. The LMM scheme implements simplified MLD proxying function on home agent to reduce the complicated multicast routing protocol and modifies MLD host part function on mobile node to reduce the multicast membership messages interaction. In order to solve the tunnel convergence problem, LMM also introduces a multicast tunnel combination and reconstruction algorithm.
