Named Data Networks (NDNs) use data names instead of host addresses to locate data. The NDN architecture assumes pull-based forwarding and a one-interest-one-data principle. To initiate a data transfer, a data consumer must send an Interest Packet to request the corresponding data packet. NDN’s chunk-based caching feature is beneficial in coping with the mobility and intermittent connectivity challenges in Mobile Ad Hoc Networks (Manets).
In a paper presented at the 2013 International Conference on Computing, Networking and Communications (ICNC 2013), researchers from the University of California, Los Angeles, and IBM T.J. Watson Research Center describe a study of Named Data Manet (NDM) forwarding designs. They propose the Neighborhood-Aware Interest Forwarding (NAIF) design to reduce the bandwidth usage induced by indiscriminate interest flooding, which is a problem in other NDM forwarding designs. They present results showing that NAIF reduces bandwidth usage by up to 54 percent compared to other approaches.
