A survey of mobility support in Named Data Networking

The initial Named Data Networking (NDN) architecture design provided consumer mobility support automatically, taking advantage of NDN's stateful forwarding plane to return data to mobile consumers; at the same time, the support of data producer mobility was left unspecified. During the past few years, a number of NDN producer mobility support schemes have been proposed. This paper provides a clear definition of NDN mobility support, to enable fetching of data produced by mobile users, and then to classify the proposed solutions by their commonalities and to articulate design tradeoffs of different approaches. We identify remaining challenges and discuss future research directions for effective and efficient data producer mobility support in NDN.
