Producer Mobility Support in 5G-ICN

Information centric networking (ICN) provides content efficiently by using name-based routing and content caching. Producers generate contents and consumers request contents by sending Interest messages. Then, either producers or content caching nodes return Data to consumers. In ICN, it is not easy to support producer mobility, since Interest packets are not successfully delivered to a producer, if the producer changes its point of attachment (PoA). Flooding, anchor, and pointer forwarding-based producer mobility support schemes have been proposed in ICN. Producer mobility support is an important issue in 5G, too, and procedures for flooding-based producer mobility support in ICN enabled 5G (5G-ICN) have been proposed recently. In this paper, we present procedures for anchor and pointer forwarding-based producer mobility support schemes in 5G-ICN. Finally, we compare flooding, anchor, and pointer forwarding-based producer mobility support schemes qualitatively in 5G-ICN.
