Matching device, terminal, sensor network system, matching method, and matching program

A matching method wherein a computer executes steps comprising:

• acquiring provider-side metadata regarding a first terminal that provides sensing data, the provider-side metadata comprising at least a current position of the first terminal,
• acquiring user-side metadata regarding condition for sensing data that is to be used by a second terminal,
• making a prediction about whether or not sensing data provided by the first terminal will satisfy the condition in the future by matching the current position of the first terminal and a current time with the user-side metadata, and deciding whether or not to request the first terminal to provide the sensing data based on a result of the prediction, and
• requesting the first terminal to provide the sensing data in accordance with the decision in the matching step.

A non-transitory computer-readable storage medium storing a matching program for causing a computer to execute operations comprising:

• acquiring provider-side metadata regarding a first terminal that provides sensing data, the provider-side metadata comprising at least a current position of the first terminal,
• acquiring user-side metadata regarding condition for sensing data that is to be used by a second terminal,
• making a prediction about whether or not sensing data provided by the first terminal will satisfy the condition in the future by matching the current position of the first terminal and a current time with the user-side metadata, and deciding whether or not to request the first terminal to provide the sensing data based on a result of the prediction, and
• requesting the first terminal to provide the sensing data in accordance with the decision in the matching step.
