On-demand Geographic Forwarding for producer mobility support in Named Data Networking
Mohammed Bellaj, Najib Naja, Abdellah Jamali · 2023
With the rapid advancement of mobile devices and the continuously increasing generated traffic have made mobility support in networks a critical requirement. Recently, named data networking (NDN) has emerged as potential alternative architecture to address the challenges of the current IP-based Internet architecture, such as scalability, privacy, and security. However, despite the implicit handling of consumer mobility in the NDN architecture, producer mobility remains a major challenge and is especially important for emerging applications such as virtual and augmented reality, IoT devices, and 5G networks. This paper introduces a new approach to handle producer mobility in NDN, called on-demand geographic forwarding (OGF). The OGF mechanism redirects Interest packets to the mobile producer's next access point location via a fixed Rendezvous server, using the location information of the access points. Our proposed solution anticipates the mobile producer's handoff and chooses the next access point before the handoff occurs. We have evaluated our proposed solution using ndnSIM simulation and compared its performance with a popular tracing-based solution called Kite, proposed by the NDN research group. The simulation results clearly illustrate that the OGF solution outperforms Kite by reducing signaling overhead by 90%, decreasing packet loss by 25%, and saving 13% of handoff delay time.
