  This paper proposes a handover scheme supporting Multi-Protocol Label
Switching (MPLS) in a Proxy Mobile IPv6 (PMIPv6) domain that improves the
mobility and gives Quality of Service (QoS) and Traffic Engineering (TE)
capabilities in wireless access networks. The proposed scheme takes advantages
of both PMIPv6 and MPLS. PMIPv6 was designed to provide NETwork-based Localized
Mobility Management (NETLMM) support to a Mobile Node (MN); therefore, the MN
does not perform any mobility related signaling, while MPLS is used as an
alternative tunneling technology between the Mobile Access Gateway (MAG) and
the Local Mobility Anchor (LMA) replacing the IP-in-IP tunnels with Label
Switched Path (LSP) tunnels. It can also be integrated with other QoS
architectures such as Differentiated Services (DiffServ) and/or Integrated
Services (IntServ). In this study, we used MATLAB to perform an analysis to
evaluate the impact of introducing MPLS technology in PMIPv6 domain based on
handover latency, operational overhead and packet loss during the handover.
This was compared with PMIPv6, and a PMIPv6/MPLS integration. We proved that
the proposed scheme can give better performance than other schemes.
