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

摘要

A network terminal, a network system, a time synchronization method, and a time synchronization program; in which the scale of the system can be suppressed; which are applicable even to ad hoc type systems; and which will enable synchronization, with the other sensor nodes (1), of the time with which time-keeping is conducted. Each of the sensor nodes (1) will calculate the average time of the time-keeping conducted by the timers (14) of the other sensor nodes (1) existing within the network, by using time serial data transferred repeatedly among the sensor nodes (1) existing in the network, and set this average time as the time for the timer (14) of its own sensor node (1).
