NETWORK TERMINAL, NETWORK SYSTEM, TIME SYNCHRONIZATION METHOD, AND TIME SYNCHRONIZATION PROGRAM

摘要

A network system capable of suppressing system scale is provided and such a system can be used even for an ad-hoc type system. The network system enables synchronization of a sensor node 1 with other sensor nodes 1 in measured time. Each sensor node 1 uses time-series data that is repeatedly transferred among the sensor nodes 1 existing on the network to calculate an average time measured by timers 14 of other sensor nodes 1 existing on the network and sets the time of the timer 14 of the own sensor node 1 to the average time.
