    abstract =  {This memo discusses the use of the Constrained Application Protocol (CoAP) protocol in building sensors and other devices that employ cellular networks as a communications medium. Building communicating devices that employ these networks is obviously well known, but this memo focuses specifically on techniques necessary to minimize power consumption.},
