Block Prefix Mechanism for Flow Mobility in PMIPv6 Based Networks

Abstract

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.

“…− LMA: the mobile node's binding status is managed by LMA, which functions as its home agent. The signaling flow of PMIPv6, as shown in Figure 5, is as follows: when a mobile node connects to MAG for the first time, it sends the router solicitation message to MAG [22]. The MAG sends a PBU message to LMA for updating.…”
