Additionally,

We wrote and implemented an I-D about IPv6 vs IPv4 consumption in 
smartphone:
https://tools.ietf.org/html/draft-petrescu-v6ops-ipv6-power-ipv4-00

We wrote, implemented and protected an I-D about an Energy Metric for 
IPv6 links:
https://www.researchgate.net/publication/281272590_Energy_Metric_for_IPv6_Links
(this was also an experiment of IPRing an Internet Draft without 
publishing it at IETF)
