Simultaneous mobility of data sources and content requesters in content-centric networking

Content-Centric Networking (CCN) is proposed as a new communication paradigm in which the content is accessed by the name instead of IP address with the benefit of mobility support. Although the mobility of the content requester is supported in CCN, it is not trivial to support the mobility of the data source node due to the changes in the content name or the long update of the routing table. Furthermore, many existing methods only consider a static content requester as the peer of the mobile data source even though it might also serve a mobile content requester. In this paper, we propose the Home AP method to support data source mobility that serves static and mobile content requesters. We verify the validity of the proposed method using the OPNET simulator. The simulation results demonstrate that the proposed method outperforms other mobility management methods.
