Most IoT (Internet of Things) developers these days are building their solutions with an approach where the Internet connectivity is taken as granted. That is, they focus very much on the application level without taking into consideration the network infrastructure. In the context of the Internet of Things, we’re talking about very constrained computing devices, that very often do not offer any sort of human-machine interface for operating purposes besides the fact that they are – hopefully – connected to the Internet. In order to manage and operate large fleets of such devices, and be able to track their overall “health” (battery level, quality of the cellular signal, etc) or upgrade them over the air, specific protocols as well as server-side infrastructure must be deployed.

The Open Mobile Alliance (OMA) is a standards body which develops open standards for the mobile phone industry like Multimedia Messaging Service (MMS), OMA Data Synchronization (OMA-DS) and OMA Device Management (OMA-DM).

OMA Lightweight M2M is a protocol for device and service management. The main purpose of this technology is to address service and management needs for constrained IoT devices, over a number of transports and bearers. 

A device which is LWM2M-ready can be managed remotely from a LWM2M server, and therefore be e.g. rebooted, upgraded, etc.
