摘要:
Provided is a method for transferring data of a sensor network system in which communication is made with multiple sensor nodes SN1s connected via a wireless network to transmit sensing data measured by the sensor nodes SN1s to a server SNS connected via a wired network. The method includes: receiving the sensing data from each of the sensor nodes SN1s (S1); adding meaning information that corresponds to a measurement value contained in the sensing data to the sensing data (S2, S5); and transmitting the sensing data to which the meaning information is added to the server SNS (S6). Accordingly, data of the sensor nodes are efficiently used by multiple applications while effectively using a reduced resource for wireless communication.

There is provided a facile sound communication tool that can quickly communicate with a necessary partner when needed. The real-time contexts of users are detected from sensors that are worn by the users, and diverse sensors that are located around the respective users to obtain data. The data is transmitted to a server. A context analyzer of a processor in the server determines the busyness of the respective users on the basis of the data, and a collaboration controller controls a communication between the respective users on the basis of the busyness.

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.
摘要:
In a sensor network system comprising a sensor terminal and a management server, the sensor terminal transmits observation data acquired using the sensor, the management server has a latest data storage manager which manages the latest observation data among observation data received from the sensor terminal, a history data storage manager which manages the history of the observation data from any time when data was received from the sensor terminal to the latest observation data, and a missing data manager which manages missing history data, and compensates the missing history data based on a predetermined rule, and when a request for such observation data is received, at least one of the latest observation data managed by the latest data storage manager, and history data wherein the missing data has been compensated and managed by the history data storage manager, is output according to the type of request.

A sensor node may be used for another purpose for a moment and may also be replaced. By configuring, for a sensor node, a logic node which is provided with the physical node use information indicating whether or not the sensor node is in use and the logical node use information indicating whether or not the sensor node is provided as a logic node, a sensor node to be replaced may be specified based on the replacement request of the sensor node, a sensor node is selected which is configured as logic node providing the physical node use information indicating that the sensor node is not used and the logic node use information indicating that the sensor node is provided as the logic node, thus selected sensor node is identified as the replacing sensor node to achieve the replacement from the replaced sensor node to the replacing sensor node.

This invention enables to easily retrieve real-time information from a large number of sensors connected to a network. The sensor network system of this invention includes distributed data processing servers for collecting data from plural sensors at a predetermined frequency, a management server for maintaining a location of sensor data, user terminals for requesting data to the management server, and a first network for connecting with the management server, user terminals and plural distributed data processing servers. The management server includes a model table having model names previously set and information link pointers for indicating which distributed data processing server collects data corresponding to the model names, and a search engine for acquiring data requested by the user terminals from the distributed data processing servers corresponding to the information link pointers based on the model table and for responding to the user terminals with the data.
