Current IP‐level mobility management protocols are unable to satisfy the stringent handover latency requirements for supporting real‐time multimedia services between different domains in a high‐speed vehicular environment. This paper proposes an inter‐domain handover scheme for Proxy Mobile IPv6 (PMIPv6) with a new network entity, called intermediate‐mobile access gateway (iMAG). The iMAG is located between the home and the foreign domains and is connected to both domains. The proposed scheme is a proactive handover approach that performs the inter‐domain L3 handover in advance before the inter‐domain L2 handover while the Mobile Node (MN) is still connected to the iMAG in the home domain. Therefore, the proposed scheme enables the inter‐domain handover latency to reduce as low as the intra‐domain handover latency. Numerical analysis and simulation results demonstrate that the proposed scheme is able to support seamless service continuity in inter‐domain handovers. Copyright © 2009 John Wiley & Sons, Ltd.
