Hi Jongdeog

NLSR does not support broadcast links
https://redmine.named-data.net/issues/4389 so this setup would not work.
You can create Ethernet unicast faces in /etc/ndn/nfd-init.sh script,
arranging all nodes in an all-pairs topology, and NLSR would work with

NFD supports self-learning but it's not optimized for wireless links.
Wireless support is to be developed in
https://redmine.named-data.net/issues/4281 but this probably needs 3~6

Yours, Junxiao
