In the era of wireless communication, mobility management is one of the most significant issues to be resolved. Current IP-level mobility protocols such as Mobile IPv6 or Proxy Mobile IPv6 (PMIPv6) have difficulties meeting the stringent handover delay requirements. Besides, when there are many candidate networks, i.e., multiple destination networks, can be selected, a proper selection of Mobile Node's destination network can improve the handover delay and packets loss. In order to reduce the limitation within heterogeneous networks, the IEEE 802.21 Media Independent Handover Services (MIH) was developed. MIH enables the optimization of handover between heterogeneous networks. In this paper, A Load-Considered Fast Media Independent Handover control scheme for Proxy Mobile IPv6 (LC-FMIH-PMIPv6) is proposed to integrate the robustness of MIH services and a proper selection of MN's destination network to improve the handover performance over the PMIPv6 environment.
