System clock synchronization in an ad hoc and infrastructure wireless networks |
摘要 |
A method of synchronizing clocks in the stations of ad hoc and infrastructure networks includes providing a time stamp field in a header; reading the header by all stations in a network; extracting the time stamp information from the header by each station in the network as time information; sending extracted time information to a station clock; and adjusting the station clock as a function of the extracted time information. A system for synchronizing clocks in the stations of ad hoc and infrastructure networks includes a DLL having a comparator for receiving the time stamp information and a low-pass filter having a long time-constant for adjusting the station clock in a gradual manner; a time stamp field in a header; and time information extracted from the time stamp information of the header by each station in the network.
