SYSTEMS AND METHODS FOR SYNCHRONIZATION WITHIN A NEIGHBORHOOD AWARE NETWORK

摘要

Methods, devices, and computer program products for synchronization of wireless devices in a peer-to-peer network are described herein. In one aspect, a method for determining at least one of a time for exiting and a time for entering a low power sleep mode to utilize a discovery window is provided. The method includes determining an earliest possible start time of a discovery window according to a clock at the first device. The method further includes transitioning from the low power sleep mode to a higher power active mode approximately at the determined earliest possible start time, wherein the determined earliest possible start time is based at least in part on a clock drift value associated with the first device and a clock drift value associated with a second device of the wireless network.

1. In a first device of a wireless network of devices, a method of determining at least one of a time for exiting and a time for entering a low power sleep mode to utilize a discovery window comprising:
determining an earliest possible start time of a discovery window according to a clock at the first device; and transitioning from the low power sleep mode to a higher power active mode approximately at the determined earliest possible start time, the determined earliest possible start time based at least in part on a clock drift value associated with the first device and a clock drift value associated with a second device of the wireless network.
