In an approach for creating a machine-to-machine device model based on ontological relationship, one or more computer processors determine a plurality of characteristics of one or more machine-to-machine devices within a machine-to-machine communication environment. The one or more computer processors determine one or more ontological relationships between the one or more machine-to-machine devices and the plurality of characteristics of the one or more machine-to-machine devices. The one or more computer processors create a semantic device model, based, at least in part, on the one or more ontological relationships between the one or more machine-to-machine devices and the plurality of characteristics of the one or more machine-to-machine devices.
