SUMMARY Many schemes have recently been proposed for the separation of identifier (ID) and locator (LOC), which include the Host Identity Protocol, the Identifier‐Locator Network Protocol, and the Locator Identifier Separation Protocol. However, all of these schemes were originally designed in fixed network environment, rather than mobile network environment. In particular, these schemes are based on a centralized map server that is used as an anchor point for mobile nodes, and thus intrinsically subject to some limitations in a mobile environment. In this paper, we propose a distributed ID‐LOC mapping management scheme in a mobile‐oriented Internet environment. In the proposed scheme, we assume that a host has a globally unique and hierarchical Host ID (HID) that contains the information of its home network domain. Each network domain has a distributed map server for distributed management of ID‐LOC mappings. For roaming support, each distributed map server maintains its own home HID register and visiting HID register, which are used to keep the mappings of HID and LOCs for mobile nodes in the distributed manner. By performance analysis, it is shown that the proposed distributed scheme can give better performance than the existing centralized schemes in terms of ID‐LOC binding update and data delivery costs.
