Abstract

In disaster situations, networks are fragmented due to the disruptions of communication infrastructure and stable connectivity between nodes is not guaranteed. Therefore, opportunistic forwarding based on delay tolerant networks (DTN) should be used for message delivery in such disaster situations. Also, information centric network (ICN) approach can be used for communication of urgent messages to first-responders or government authorities in disaster situations. For efficient communication in disaster situations, therefore, ICN and DTN should be interworked. In this paper, we propose an opportunistic DTN-based forwarding scheme of Interest and Data for ICN in disaster situations.
