Abstract:
According to a sensor network system and a method for processing sensor data, a sink node collects sensor data from sensor nodes, performs a prediction algorithm which is the same as a prediction algorithm performed in the sensor node to obtain a prediction value, when a sensing value is received from the sensor node, updates the prediction value to the sensing value, stores the sensing value as sensor data, determines whether the sensor node is a representative node when the sensing value is not received from the sensor node, and stores the prediction value as sensor data if the sensor node is the representative node, and corrects the prediction value based on the sensing value of a representative node and stores the corrected prediction value as sensor data if the sensor node is not the representative node.
Abstract:
Provided is a device and a method for smart device and sensor node integrated application update, including an application program updating device including a generator to generate a package in a storage space by installing a sensing application, an extractor to extract an installation file and a profile of an application program interworking with the sensing application from the package, a recognizer to recognize a sensor node by referring to the profile, an installer to install the application program by transmitting the installation file to the sensor node, and an executor to execute the application program and the sensing application when the application program is installed in the sensor node.
Abstract:
An apparatus and method for processing a path management packet is provided, the method including determining whether a router for processing a received path management packet is a storing node, and when the router is determined to be a storing node, controlling the path management packet to be stored in a routing table, or when the router is determined to be a non-storing node, failing to store the path management packet in the routing table and controlling the path management packet to be transmitted to a subsequent node.
