1. Introduction
In Information centric network (ICN), a node requests Data by
sending Interest packet and this Interest packet is forwarded
through ICN routers. A router with the requested Data replies to the
Interest to the requester and the Interest is delivered through a
reverse path of the forwarded Interest. ICN router manages content
store (CS), pending interest table (PIT), and forwarding information
base (FIB) [George2014]. In CS, cached data is stored for future use.
In PIT, the information of Interest, the incoming and outgoing faces
of the Interest are stored, and this information is used to deliver
Data to the requester using the reverse path of forwarded Interest.
FIB is used to forward Interest to appropriate faces.
ICN is considered important for communication of urgent messages in
disaster situations [Edo2014]. In disaster situations, communication
infrastructure is destroyed and networks are fragmented. In
fragmented networks where connectivity between the nodes at
different fragmented networks is not possible, opportunistic network
such as delay tolerant networks (DTN) can be used to deliver
messages. In DTN, a message is delivered to a destination node via
