In IP-based wireless networks, minimizing handover latency with few packet loss is one of the most important issues. To achieve this goal, host-based and network-based fast or localized mobility management solutions have been proposed. Proxy Mobile IPv6(PMIPv6) avoids tunneling overhead over the air and supports mobility for hosts without host involvement. However, the basic performance of PMIPv6 for handover latency and packet loss is not different from that of Mobile IPv6.In this paper, we propose an enhancement for PMIPv6 to reduce the packet reception latencyand to minimize packet lossfor both intra-local mobility anchor(LMA) and inter-LMA handover by pre-establishing bidirectional tunnel between MAGs within an administrative domain. As a result, we found that the proposed scheme, though it requires additional signaling messages to establish the bidirectional tunnels, guarantees lower packet reception latency and fewer packet loss than other recent approaches without erroneous movement prediction.
