Systems and methods for optimization of synchronization message transmission intervals in a peer-to-peer network

摘要

Methods, devices, and computer program products for optimization of synchronization message transmission intervals in a peer-to-peer network are described herein. In one aspect, a method for determining an optimized timing for synchronization messages is provided. The method includes receiving clock drift information from other devices on the peer-to-peer wireless communication network. This clock drift information may be used to determine the frequency with which new synchronization messages must be sent in order to keep synchronization error under a certain requirement at other devices, while minimizing the network traffic due to the transmissions of synchronization messages.

1. A root device in an ad-hoc wireless communication network comprising:
a receiver configured to receive a message from other devices in the network, the message including drift information of clocks of other devices in the network, wherein the drift information comprises a maximum network clock drift and a minimum network clock drift; a processor configured to:
determine an adjusted maximum network clock drift based on a maximum clock drift of the wireless device and the maximum network clock drift;determine an adjusted minimum network clock drift based on a minimum clock drift of the wireless device and the minimum network clock drift; andset a timing of synchronization frames based, at least in part, on the drift information, a clock drift of the root device, the adjusted maximum network clock drift, and the adjusted minimum network clock drift; and a transmitter configured to transmit synchronization frames in accordance with the set timings.
