MsDD: A novel NDN producer mobility support scheme based on multi-satellite data depot

Area of Science:

• Computer Science
• Networking
• Satellite Communications

Background:

• Named Data Networking (NDN) is a key future network architecture.
• Producer mobility in NDN causes significant consumer delays and data loss.
• Existing solutions struggle with frequent producer mobility in NDN.

Purpose of the Study:

• To propose a novel producer mobility support scheme for NDN.
• To leverage multi-satellite data depots for enhanced NDN performance.
• To address the limitations of traditional schemes in mobile NDN environments.

Main Methods:

• Developed a multi-satellite data depot (MsDD) scheme for NDN.
• Designed data depot construction, in-network caching, and forwarding hint-based routing strategies.
• Utilized ndnSIM for experimental validation.

Main Results:

• MsDD effectively mitigates the impact of producer mobility on consumer delay and delivery ratio.
• The proposed scheme significantly reduces signaling overhead compared to existing methods.
• Experimental results show MsDD's clear advantages in consumer delay and delivery ratio.

Conclusions:

• MsDD offers a robust solution for NDN producer mobility, especially in 6G contexts.
• Integrating satellite networks with NDN via data depots enhances network performance.
• The scheme provides a scalable and efficient approach for future mobile networks.
