A Novel Handover Mechanism of PMIPv6 for the Support of Multi-Homing Based on Virtual Interface

Abstract

The Proxy Mobile IPv6 (PMIPv6) is a network-based accessibility managing protocol. Because of PMIPv6’s network-based approach, it accumulates the following additional benefits, such as discovery, efficiency. Nonetheless, PMIPv6 has inadequate sustenance for multi-homing mechanisms, since every mobility session must be handled through a different binding cache entry (BCE) at a local mobility anchor (LMA) according to the PMIPv6 specification, and thus PMIPv6 merely permits concurrent admittance for the mobile node (MN) which is present in the multi-homing concept. Consequently, when a multi-homed MN interface is detached from its admittance network, the LMA removes its moving part from the BCE, and the current flows connected with the apart interface are not transmitted to the multi-homed MN, even if a more multi-homed MN interface is still linked to another access network. A superior multi-homing support proposal is proposed to afford flawless mobility among the interfaces for a multi-homed MN to address this problem. The projected method can shift an application from a disconnected interface of a multi-home MN to an attached interface using the PMIPv6 fields of Auxiliary Advertisement of Neighbor Detection (AAND).
