Abstract: 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 synchronizing a wireless communication apparatus is provided. The method includes receiving one or more synchronization messages, each synchronization message having timing information and a cluster identifier, the timing information comprising anchor timing information, the cluster identifier being the same value as a cluster identifier of the apparatus. The method further includes determining whether a difference between a time value when a received synchronization message last received anchor timing information and a time value maintained for the apparatus is greater than a threshold. The method further includes discarding the received synchronization message if the difference exceeds the threshold.

Abstract: Methods, systems, and devices are described for communications via a mesh network. To join an existing mesh network, a wireless communication device may identify a member device from a plurality of member devices of an existing mesh network. The wireless communication device may communicate with the identified member device to participate in a single authentication procedure. Upon successfully completing the single authentication procedure, the wireless communication device may join the existing mesh network without needing any additional authentication procedures with another member device of the plurality of member devices to join the existing mesh network. This approach may be used for any mesh network, such as a social Wi-Fi mesh network.
