OBJECT SENSOR NODE, MANAGER SINK NODE FOR OBJECT MANAGEMENT AND OBJECT MANAGEMENT METHOD

摘要

An entity sensor node for entity management, a manager sink node, and an entity management method are provided to enable a manager to confirm the state of each entity having mobility in real time by forwarding the location information and sensing information of each entity, to which an entity sensor node having a communication function is attached, to a manager sink node through a sensor network. An entity sensor node(200), connected with a manager sink node through a sensor network, comprises a sensor part, a data processing part(220), and a situation cognition processing part(230). The sensor part measures surroundings and creates sensing information. The data processing part(220) communicates with one or more neighbor entity sensor nodes, acquires the location information of the neighbor entity sensor nodes, and transmits the acquired location information and associated sensing information according to a request from the manager sink node. The situation cognition processing part(230), if a measured value contained in the sensing information exceeds a preset critical value, generates an alarm, and transmits an alarm message to the manager sink node.
