Abstract

Methods, devices, and computer program products for hierarchical time source usage in near-me area network discovery and synchronization are described herein. In one aspect, a method for determining a discovery period using a hierarchy of external timing sources is provided. The method includes receiving an external timing signal from one or more external timing sources, and then using a hierarchy of external timing sources to determine which external timing source to use. The method further provides determining an offset from that external timing source, and using the external timing source and the offset to determine a discovery interval, in which to attempt to locate a near-me area network (NAN), such as a Social-WiFi network.
