Dear Muhammad Sajjad Akbar. Thanks for your comments and interest.
Regarding your question, I agree your point. Some link layer technologies are missing the adjustment with IoT services but the direct modification or enhancement of of them is not the scope of 6lo WG and this draft. Actually, to efficiently transmit IPv6 over these link layer technologies, we have discussed with organizations such as NFC forum and Bluetooth SIG, etc. Because the IETF 6lo WG is targeting on IPv6 connectivity over constrained node networks with the characteristics of limited power, memory and processing resources, the scope of this draft might be the local environment. But if you look the use cases in this draft, it also handles more broader scope. I think that the scope (local or wide) is not important and the more importing thing is how to deliver practical deployment scenarios and use cases with 6lo technologies for IoT services.
