Information-centric Routing for Opportunistic Wireless Networks

DABBER aims to extend the reach of Name-Data Networking (NDN) to opportunistic wireless networks, while: i) avoid flooding the network with Interest packets, which is a major requirement of opportunistic networks; ii) selective forwarding of Interest packets based on data reachability information, and context awareness (neighborhood and node itself).

The motivation behind DABBER is the lack of forwarding/routing proposals for NDN over opportunistic wireless networks. There are an extensive number of (forwarding) proposals for opportunistic wireless networks (e.g. dLife, Scorp), and an initial set of routing proposals for wired NDN networks (e.g. OSPFN, NSLR). But NO routing protocol to support NDN communications in wireless networks.

Basic differences towards version 00 are:
    • The FIB ranking operation was removed in other to be compatible with the current NFD implementation, which does not allow any operation to the done at the FIB level.
    • Better explanation of the relationship towards NSLR: Although DABBER specification allows an easier integration with NDN access networks based on NSLR, its operation is completely independent of NSLR.
    • Revised explanation of the Multiple Path Computation based on adjustments done during the implementation.
