Abstract(in Japanese) (See Japanese page)
Abstract(in English) In the field of environmental observations and measurements, a network is often constructed with wireless LANs because a lot of nodes are set up in a wide range. The time synchronization between measurement nodes is important in those wireless LANs, since the clock synchronous accuracy among nodes is critical to analysis of measured results. It is, however, difficult to have such a high accurate synchronization in wireless LANs. This paper proposes a design and implementation of IEEE1588 (Precision Time Protocol, PTP) within wireless LANs. As the first step, basic messages and processes of IEEE1588 is developed, and a experiment shows that the proposed method realizes the timing shift between master and slave clocks to be about 2.64μs.
