Abstract

In order to easily provide data successively generated from a real world sensor network in a time series to a user, a unit for generally and flexibly performing mapping between a source for generating physical electronic information (for example, a tiny sensor node) and sensing data to be provided to the user is provided. Therefore, a manager of the sensor network is composed of a device management table for mapping among a wireless sensor node, a wireless base station, and a data managing server, a real world model table capable of including device information and giving plural attributes, a registration/search processing unit for registering/searching that information, and a data manager for data mapping between the tables.
