Dear all

Within the European UMOBILE project (http://http://umobile-project.eu/ <http://http//umobile-project.eu/>) we are working on methods to extend NDN towards opportunistic wireless networks. In this context we have been implementing an NFD extension, called NDN-OPP, which supports NDN multi-hop wireless communication: NDN-OPP V1.0 for Android (to be released until Monday) does broadcast of Interest packets over a Wi-Fi direct network. 

In order to reduce resource consumption in a NDN multi-hop wireless networks, we created the DABBER routing protocol, which allows selective forwarding of Interest packets based on the local announcement of name prefixes + node awareness about the properties of neighbour nodes (centrality and availability).

Although DABBER aims to operate on a point-to-point wireless network (e.g. Wi-Fi direct) or a broadcast network (e.g. ah-hoc Wi-Fi), we are starting implementing DABBER on top of NDN-OPP, which v1.0 makes usage of Wi-Fi direct. 

In the meantime I would like to get your comment about this proposal aiming to further discuss it on the ICNRG meeting at IETF 101 in London.

Abstract:
  This draft describes the Data reAchaBility BasEd Routing (DABBER)
  protocol, which has been developed to extend the reached of Named
  Data Networking based routing approaches to 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 towards the most suitable data source, based on
  metrics that provide information about: i) the availability of
  different data sources; ii) the availability and centrality of
  neighbor nodes; iii) the time lapse between forwarding Interest
  packets and receiving the corresponding data packets. The document
  presents an architectural overview of DABBER followed by
  specification options related to the dissemination of name-prefix
  information to support the computation of next hops, and the ranking
  of forwarding options based on the best set of neighbors to ensure a
  short time-to-completion.

Melhores Cumprimentos / Best Regards / Mit freundlichen Grüßen
