| Summary: | Named Data Networking (NDN) is the most remarkable initiative of Information-Centric Network (ICN) to improve overall network performance. With its data-centric architecture and forwarding philosophy, NDN natively addressed consumer mobility. However, the producer mobility problem remains a challenging issue in NDN architecture. Among the critical issues of producer mobility are handover latency, Interest packet loss, and Interest retransmission. This paper classifies existing producer mobility solutions into rendezvous, anchor-based, and anchor-less approaches. Despite the efforts of many researchers poured into solving these issues, there is still room for improvement. This paper proposes a producer mobility management mechanism based on a proactive approach to managing producer mobility in NDN. The proposed mechanism proactively evaluates the handover time of the producer and sends the mobility notification packet to inform about the producer’s movement. In the meantime, a new Interest packet for the moving producer will be buffered on the router. Thus, the proposed mechanism aims to reduce the handover latency and packet loss. © 2024, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
