A mobility link service in NDN face to support consumer mobility service

Abstract

Named Data Networking (NDN) supports the consumer mobility service by letting a consumer reissue an interest for the content not received during handover. A pair of an interest and a data packet in NDN can be considered as a single communication working set (i.e., transaction). In this regard, reissuing an interest means creating a new transaction due to the connection damaged by the movement of a consumer. It makes all states of the current transaction useless. In order to enhance the consumer mobility service, we propose a mobility link service operated in NDN face which is responsible for management of a connection for a transaction. It establishes a new connection for a transaction, and it hides the distortion of the connection to the transaction. By embedding a mobility link service to NDN face, the consumer mobility service is transparent to the rest of NDN architecture. Therefore, the consumer mobility service and the NDN architecture can be evolved independently. The analytical investigation and the simulation result show that the proposed scheme reduces the amount of the retransmitted data and the handover latency compared with the original NDN mobility solution.
