Information-centric Routing for Opportunistic Wireless Networks
draft-mendes-icnrg-dabber-05
Abstract
This draft describes the Data reAchaBility BasEd Routing (DABBER)
protocol. DABBER aims to provide a name-based routing solution to
support the operation of Information-centric Networking frameworks in
opportunistic wireless 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 packets in a store-
carry-and-forward manner, based on a proactive approach. The
document describes how to integrate DABBER in a networking node that
implements some ICN approach, such as Named-Data Networking (NDN) or
Content Centric Networking (CCN), along with the specification of the
proactive approach based on the dissemination of name-prefix
information.
