[Ndn-interest] Hyperbolic routing in mobile scenarios

[Lan Wang (lanwang)]

Hi Thiago,

Thank you for the question.  The answer depends on how mobile the nodes are:

1.  if the nodes are in general static and

    1a. if nodes only occasionally move in a small region, forwarding strategy can take care of some mobility by trying different faces if the face that usually leads to a node doesn’t work;

    1b. if a node moves from one network to another network and gains new coordinates belonging to the new network, then the mapping between their content names and the coordinates may be updated in the mapping system so the new coordinates can be distributed or looked up;

2. if nodes are highly dynamic like in an ad hoc network, I’m not aware of any hyperbolic routing work in this area and it could be a potentially interesting research area.  If you find such work, I would be glad to know.

Hi all,

I have been reading about hyperbolic routing in NDN and how Interest/Data packets can be routed without the full knowledge of the network, through the hyperbolic coordinates and greedy routing; however, in all examples I’ve seen, the nodes are fixed.
Has anybody studied hyperbolic routing in mobile topologies?

Cheers,
Thiago
