Double-Lead Content Search Scheme for Producer Mobility in Named Data Networking
Huilin Liu, Xushan Chen, Guoxin Xia, Hui Guo · 2020
In Named Data Networking (NDN), the processing of the packet is based on the data rather than the communication endpoint. It's very suitable for the core demand of content sharing on the internet today. However, there are still some problems to be dealt with, including mobility support of the producer. By analyzing existing solutions, we put forward a solution finding MCS (Mobile Content Source) passively by HR(Home Repository) and leading interest packets to find MCS actively in the local scope at the same time to speed up to search MCS and to support NDN producer mobility. Triangle routing problem in single HR and low efficiency problem can be based on this solution. Experimental results show that our scheme does better in reducing delay with low handoff cost than other typical solutions.
