Named Data Networking (NDN) natively supports the mobility of active data consumers with its data-centric nature and stateful forwarding plane. However, the mobility support for producers and passive consumers was a missing piece in the original proposal. In this paper, we introduce Kite, an NDN-inspired mobility support scheme for NDN. By leveraging the traces of Interests in Pending Interest Tables (PITs) to reach mobile nodes, Kite achieves locator-freeness which makes the location of mobile node transparent to all parties in communications. With Kite, we present the scenario-aware protocol designs for typical scenarios including group communication among mobiles. Kite outperforms the mapping-based conceptual scheme in terms of path stretch and mobile delay, while costing similar signaling overhead in the case of high-frequent movement. We also discuss security considerations and architectural implications on NDN.
