Towards a Sustainable Digital Society: Supporting Producer Mobility in Named Data Networking Through Immobile Anchor-Based Mechanism

The increasing proliferation of intelligent mobile devices and the subsequent surge in data traffic have placed a burden on the current Internet infrastructure. To address this challenge, Named Data Networking (NDN) has emerged as a promising future Internet architecture. NDN aims to address the evolving patterns of Internet traffic by providing inherent support for consumer mobility through in-network caching. This approach enhances content availability while minimizing delays. However, producer mobility in NDN raises numerous challenges, including Interest packet loss, Interest retransmission, high signalling costs, and unnecessary bandwidth consumption. This research explores and critically analyses the most widely used approaches for managing producer mobility in NDN. This paper introduces an innovative immobile anchor-based mobility mechanism designed to address the challenges associated with producer mobility in NDN. The immobile refers to the fixed nature of the anchor router, which is strategically placed within the network topology to facilitate the management of producer mobility. This immobile anchor router serves as a centralized control point for caching and redirecting Interest packets during producer handoff processes, thereby mitigating packet loss and optimizing bandwidth usage. The focal point of this novel approach is to reduce the repercussions of producer mobility on network performance. Its aim is to minimize factors like packet loss, signalling overhead, and bandwidth usage, with the ultimate goal of enhancing the overall efficiency of NDN-based networks.
