Shim Header for CoAP Transfer over non-TCP/IP Networks
Namhi Kang, Seung-Hun Oh, Byoung-Tak Lee, Ilkyun Park, Sim-Kwon Yoon · 2014
This document defines shim header for the transfer of CoAP messages over non-TCP/IP constrained networks. In this environment, IP and UDP or TCP are not used, so that additional shim header as a container for addresses of sender/receiver and the length of CoAP header and its payload is required.
