Domain‐based distributed identifier‐locator mapping management in Internet‐of‐Things networks

摘要

Recently, a lot of studies on identifier-locator mapping management for mobility control have been proposed. However, these studies did not consider the Internet-of-Things (IoT) environment. Thus, from the viewpoint of identifier-locator mapping management for IoT devices, the existing schemes are still subject to scalability problems and performance degradation. In this paper, we propose a domain-based identifier-locator mapping management for IoT devices in a distributed manner, in which an identifier of IoT device represents the domain to which it belongs. Each domain gateway maintains the mapping information of identifiers and locators based on the domain information contained in the identifier. From the numerical analysis and testbed experimentation, we see that the proposed domain-based distributed identifier-locator mapping management scheme provides better performance than the existing schemes in terms of total delay, including registration delay and data delivery delay.
