Proxy Mobile IPV6 (PMIPV6) is a network-based mobility management protocol, designed to keep track of individual mobile node's movement. So a mobile node can easily roam in PMIPV6 network without changing it's IP address. Network Mobility-Basic Support Protocol (NEMO-BSP), based on MIPV6, is the protocol designed for mobility management of NEMO in MPIV6 network. But NEMO-BSP cannot be directly used in PMIPV6 due to differences in the underlying protocols. To make PMIPV6 as a complete mobility management protocol, functionality of PMIPV6 should be enhanced to support network mobility in PMIPV6. This work enhances functionality of PMIPV6 and NEMO-BSP protocols and proposes a new architecture called NEMO supported PMIPV6 that supports movement of mobile nodes as well as network mobility in PMIPV6 network.
Proxy Mobile IPV6 (PMIPV6) is a network based mobility management protocol which supports node's mobility without the contribution from the respective mobile node. PMIPV6 is initially designed to support individual node mobility and it should be enhanced to support mobile network movement. NEMO-BSP is an existing protocol to support network mobility (NEMO) in PMIPV6 network. Due to the underlying differences in basic protocols, NEMO-BSP cannot be directly applied to PMIPV6 network. Mobility management signaling and data structures used for individual node's mobility should be modified to support group nodes' mobility management efficiently. Though a lot of research work is in progress to implement mobile network movement in PMIPV6, it is not yet standardized and each suffers with different shortcomings. This research work proposes modifications in NEMO-BSP and PMIPV6 to achieve NEMO support in PMIPV6. It mainly concentrates on optimizing the number and size of mobility signaling exchanged while mobile network or mobile network node changes its access point.
