Abstract
Proxy Mobile IPV6 (PMIPV6) is a network-based mobility management protocol, designed to keep track of individual mobile node’ 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.
Highlights
This study proposes necessary enhancements to PMIPV6 and NEMO-BSP protocols to support mobile network movement in PMIPV6 network
Load on LMA and Mobile Access Gateway (MAG) of proposed architecture is compared with the architecture simulated with basic PMIPV6 and NEMO-BSP, which is slightly modified to register all mobile nodes in mobile network with LMA
This research paper proposes enhancement to both NEMO-BSP and PMIPV6 to enable tracking of mobile network movement along with tracking of individual mobile node movements in PMIPV6 network
Summary
PMIPV6 (Gundavelli et al, 2008; Gundavelli, 2012) is designed to track mobility of individual mobile node. The network elements such as Local Mobility Anchor in PMIPV6 Network. The issues encountered while mobile network roams inside PMIPV6 network are given below. (LMA) and Mobile Access Gateway (MAG) track mobile node’s movement in PMIPV6 network. Mobile nodes can be free from their own mobility management and roam in PMIPV6 network. In situations where group of nodes move together like nodes in aircraft or bus, it is overhead and unnecessary to track individual node’s mobility and enough to track network mobility as a whole. NEMO-BSP supports mobile network movement in MIPV6 network. NEMO-BSP cannot be directly used in PMIPV6. Complete support of NEMO in PMIPV6 requires modification in both NEMO-BSP and PMIPV6, as per the research in this area (Bernardos et al, 2012; Jeon and Kim, 2011a)
