Apparatus and method for generating virtual sensor in sensor network

摘要

A virtual sensor generation apparatus of a sensor network sets a communication connection to a sensor node at a periphery of a smart device, generates a logical sensor corresponding to a physical sensor that is connected to the sensor node, generates a virtual sensor with the logical sensor, and provides an application service to a user using the virtual sensor.

主权项

1. A virtual sensor generation apparatus of a smart device, comprising:
a sensor node coordinator that sets a communication connection from the smart device to a sensor node at a periphery of the smart device upon the smart device entering a sensor network area, and receives, from the sensor node via the communication connection, a plurality of profiles, each profile being that of the sensor node or that of one of a plurality of physical sensors connected to the sensor node; a logic sensor manager that generates at least one logical sensor corresponding to at least one of the plurality of physical sensors of the sensor node, and assigns the profile of the at least one physical sensor to the at least one logical sensor; a virtual sensor manager that generates a virtual sensor using the at least one logical sensor and at least one of previously generated virtual sensors; and a service manager that generates an application service using an application programming interface (API) of the at least logical sensor and the at least one virtual sensor and that provides the application service to a user.
