Block Prefix Mechanism for Flow Mobility in PMIPv6 Based Networks
The next generation Internet is deemed to be heterogeneous in nature and
mobile devices connected to the Internet are expected to be equipped with
different wireless network interfaces. As seamless mobility is important in
such networks, handover between different network types, called vertical
handover, is an important issue in such networks. While proposing standards
like Mobile IPv6 (MIPv6) and Proxy Mobile IPv6 (PMIPv6) for mobility management
protocols, one important challenge being addressed by IETF work groups and the
research community is flow mobility in multi-homed heterogeneous wireless
networks. In this paper we propose and analyze a block prefix mechanism for
flow mobility in PMIPv6 and conducted extensive analytical and simulation
studies to compare the proposed mechanism with existing prefix based mechanisms
for flow mobility in PMIPv6 reported in terms of important performance metrics
such as handover latency, average hop delay, packet density, signaling cost and
packet loss. Both analytical and simulation results demonstrate that the
proposed mechanism outperforms the existing flow mobility management procedures
using either shared or unique prefixes
