    Information-centric Routing for Opportunistic Wireless Networks
                      draft-mendes-icnrg-dabber-04

Abstract

   This draft describes the Data reAchaBility BasEd Routing (DABBER)
   protocol, which aims to extend the operation of distributed
   Information Centric Networking frameworks to opportunistic wireless
   networks such as Delay Tolerant Networks.  By "opportunistic wireless
   networks" it is meant multi-hop wireless networks where finding an
   end-to-end path between any pair of nodes at any moment in time may
   be a challenge.  The goal is to assist in better defining
   opportunities for the transmission of Interest and Data packets in a
   store-carry-and-forward manner, based on a combination of proactive
   and reactive approaches.  The document presents an architectural
   overview of DABBER followed by the specification of the proactive
   approach based on the dissemination of name-prefix information, and
   the reactive approach based on the encounters probability.
