This looks to be a well-written and detailed specification for an ICN adaptation to LowPAN networks. 

Drafts to be published as RFCs in the IRTF stream need to include various notices, as described in RFC 5743 Section 2.1. Some of those notices look to be missing from this draft and will need to be added before it can be published. 

It’s also important for a draft to be published as an Experimental RFC to be clear about what experiment being performed. Section 10 of the draft includes a brief implementation report, describing experiments that have been conducted using this protocol, which is good, but the draft says very little about what experiments remain to be done and what can be learnt from further experimental deployment of this protocol. Would it be possible to add some additional context about how this fits with ongoing experiments in this space?
