摘要：Proxy Mobile IPV6 (PMIPV6) is a networkbased mobility management protocol, designed to keep track of individual mobile node’s mobility. Numerous research works are in progress to enhance functionality of PMIPV6 to support NEtwork MObility (NEMO) as well. NEMOBSP (NEMO Basic Support Protocol) is the protocol designed for NEMO and it is the extension of MIPV6. But NEMOBSP cannot be directly used in PMIPV6 due to differences in the underlying protocols. IETF standard has given many design criterions for the protocol which supports NEMO in PMIPV6. This research work concentrates on two among the design considerations called “Resourceefficient handoff management” and “Minimal packet loss during handoff”. While mobile network changes its point of attachment in PMIPV6 network, lot of Binding updates (BU) and Binding acknowledgements (BA) are sent overtheair to handoff, to register new location of nodes in mobile network and acquire network prefix for them. By using the fact that all nodes in the mobile network move together, this research work combines individual BU and BA of all nodes in mobile network and sends them together. By grouping the BUs and BAs, handover time and number of signaling messages to be exchanged during mobile network movement are reduced drastically.
