The Open Mobile Alliance (OMA) announced that the popular LightweightM2M (LwM2M) version 1.0 specification has moved from Candidate Release status to Approved Release status. The OMA Board of Directors passed the motion to move the specification to Approved status at its meeting held February 9, 2017 in Vancouver, Canada.
OMA’s LightweightM2M (LwM2M) is a device management protocol designed for sensor networks and the demands of a machine-to-machine (M2M) environment. With LwM2M, OMA has responded to market demand for a common standard for managing lightweight and low power devices on a variety of networks necessary to realize the potential of IoT. The LwM2M protocol features a modern architectural design based on REST, defines an extensible resource and data model and reuses and builds upon an efficient secure data transfer standard called the Constrained Application Protocol (CoAP). CoAP is standardized by the Internet Engineering Taskforce (IETF) as a variation of the Internet’s HTTP. LwM2M has been specified by a group of industry experts in OMA’s Device Management Working Group and is based on protocol and security standards from the IETF.
