Patent ID: 7181470

Claim:
A data coincident method among elements which connect with other elements located in a nearby area, comprising the steps of: a first step for determining whether or not a previously defined event as a starting trigger of a coincidence processing has occurred with respect to one of said elements if an established time arrives or a time period of an established cycle has elapsed since the execution of previous information coincidence processing; a second step for acquiring a group of said elements corresponding to said one of said elements if said previously defined event has occurred at the first step a third step for transmitting a coincidence request by wireless communication to said group of elements if said previously defined event has occurred at the first step; a fourth step for one of said elements to transmit a common data by wireless communication in response to said coincidence request at the third step; a fifth step for determining whether or not said common data for one of the elements must be updated according to the largest number of the common data and significance level corresponding to a data update obtained from a group of the elements at the fourth step; and a sixth step for updating said common data for one of the elements by using the common data held among the largest number of the common data and significance level obtained from the group of the elements at the fourth step, being a majority of said elements, and returning to said first step, whereby if all of the data obtained from the group of the elements at the fourth step are not coincident, coincidence processing is repeated until all of the data is coincident.
