Systems, methods, and instrumentalities may be provided to discover a personal Internet of Things (loT) network (PIN). A discovery policy configuration information associated with a PIN may be determined. The discovery policy configuration information may comprise a PIN identification (ID) and may indicate that discovery for the PIN may be enabled. A first message may be sent to a second WTRU if discovery for the PIN is enabled. The first message may be based on the discovery policy configuration information and may indicate the PIN ID. A second message may be received from the second WTRU. The second message may indicate the PIN ID and may indicate a request for information associated with the PIN. A third message may be sent to the second WTRU. The third message may indicate the PIN ID and may indicate the requested information that may be associated with the PIN.
