1. A method comprising:
- by a server, sending at a pre-determined polling frequency an activation signal waking from a sleep mode an application on a mobile computing device of a first user and causing the application to activate a location service of the mobile computing device for a time period of a pre-determined sampling duration, the pre-determined polling frequency and the pre-determined sampling duration being determined at least in part by detecting a movement of the mobile computing device;
by the server, receiving location data from the mobile computing device after the pre-determined sampling duration,by the server, accessing a social graph of a social-networking system, the first user being a user of the social-networking system;
by the server, determining whether a current location of one or more second users is within a pre-determined proximity from the first user based on the received location data of the mobile computing device, the second users being users of the social-networking system and connected to the first user within the social graph; and
by the server, when it is determined that the current location of a second user of the one or more second users is within the pre-determined proximity from the first user, notifying the first user of the location of the second user.

Abstract
In one embodiment, a method includes transmitting at a pre-determined polling frequency an activation signal waking from a sleep mode an application on a mobile computing device and causing the application to activate a location service of the mobile computing device for a pre-determined sampling duration. The pre-determined polling frequency and the pre-determined sampling duration are determined at least in part by detecting a movement of the mobile computing device. The method also includes receiving location data from the mobile computing device after the pre-determined sampling duration. The location data is responsive to a transmission signal.

13. A device comprising:
-
a processor coupled to a storage; and one or more computer-readable non-transitory storage media coupled to the processor and embodying software configured when executed to; send at a pre-determined polling frequency an activation signal waking from a sleep mode an application on a mobile computing device of a first user and causing the application to activate a location service of the mobile computing device for a time period of a pre-determined sampling duration, the pre-determined polling frequency and the pre-determined sampling duration being determined at least in part by detecting a movement of the mobile computing device; receive location data from the mobile computing device after the pre-determined sampling duration; access a social graph of a social-networking system, the first user being a user of the social-networking system; determine whether a current location of one or more second users is within a pre-determined proximity from the first user based on the received location data of the mobile computing device, the second users being users of the social-networking system and connected to the first user within the social graph; and when it is determined that the current location of a second user of the one or more second users is within the pre-determined proximity from the first user, notify the first user of the location of the second user. - View Dependent Claims (14, 15, 16, 17, 18)
