 Research Directions for Using Information-Centric Networking (ICN) in
                           Disaster Scenarios

Abstract

   Information-Centric Networking (ICN) is a new paradigm where the
   network provides users with named content instead of communication
   channels between hosts.  This document outlines some research
   directions for ICN with respect to applying ICN approaches for coping
   with natural or human-generated, large-scale disasters.  This
   document is a product of the Information-Centric Networking Research
   Group (ICNRG).

1.  Introduction

   This document summarizes some research challenges for coping with
   natural or human-generated, large-scale disasters.  In particular,
   the document discusses potential research directions for applying
   Information-Centric Networking (ICN) to address these challenges.

   Research and standardization approaches exist (for instance, see the
   work and discussions in the concluded IRTF DTN Research Group [dtnrg]
   and in the IETF DTN Working Group [dtnwg]).  In addition, a published
   Experimental RFC in the IRTF Stream [RFC5050] discusses Delay-
   Tolerant Networking (DTN), which is a key necessity for communicating
   in the disaster scenarios we are considering in this document.
   'Disconnection tolerance' can thus be achieved with these existing
   DTN approaches.  However, while these approaches can provide
   independence from an existing communication infrastructure (which
   indeed may not work anymore after a disaster has happened), ICN
   offers key concepts, such as new naming schemes and innovative
   multicast communication, which together enable many essential
   (publish/subscribe-based) use cases for communication after a
   disaster (e.g., message prioritization, one-to-many delivery of
   messages, group communication among rescue teams, and the use cases
   discussed in Section 4).  One could add such features to existing DTN
   protocols and solutions; however, in this document, we explore the
   use of ICN as a starting point for building a communication
   architecture that supports (somewhat limited) communication
   capabilities after a disaster.  We discuss the relationship between
   the ICN approaches (for enabling communication after a disaster)
