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
   opportunistic contacts between intermediate nodes in a store-carry-
