英文摘要 | In this paper, we propose a reliable mobile multicast protocol, RRBMoM (Reliable RangeBased Mobile Multicast), in IP networks using Mobile IP. RRBMoM is an extension of RBMoM[9]. It provides ACK-based reliability and hybrid local server-initiated and sender-initiated lossrecovery, and uses a tree-based hierarchical structure to alleviate the acknowledgment-implosionproblem. A multicast home agent (MHA) acks as a representative of a set of mobile receivers whichare roaming within its service range. Only the MHA's send acknowledgments to the sender, insteadof all receivers sending their acknowledgments to the sender to prevent acknowledgment-implosion.In addition, the scheme of handoff loss recovery leads to improved throughput and end-to-end delayat the cost of additional backup nodes in the multicast tree. This cost can be dynamically controlledby adjusting a system parameter (i.e., service range). Performance results show that RRBMoM isefficient and adaptive to the dynamics of the system. |
