Abstract:
PURPOSE: A sensor node and a method for configuring a sensor node are provided to guarantee for sensor node hardware configuration required according to a condition and a situation. CONSTITUTION: When shape setting information for configuration of an in-module sensor is changed, a sensor module transmits a sensor setup signal to a node module(S504). The sensor module receives a control signal corresponding to the sensor setup signal from the node module(S505). The sensor module sets an embedded sensor(S506). After the set embedded sensor is activated, the sensor module transmits a completion signal to the node module(S507,S508).
Abstract:
The present invention relates to a framework device of a mobile terminal and a component interoperability guaranteeing method, and is configured by a hardware component generated by a developer and hardware middleware to be linked by a software (or another hardware) component. Therefore, in the exemplary embodiment of the present invention, hardware dependent parts in the hardware component are provided to the hardware middleware through setting parameters so that the hardware middleware is linked with the corresponding hardware component. The hardware middleware receives a request message according to the general inter- ORB protocol (GIOP) transmission system used for the basic communication system of the framework, parses the request message, and converts and transmits data to the corresponding hardware component. The hardware component (hardware logic) to which the request message is transmitted uses data to perform its unique function, and the result is configured as a response message by the hardware middleware and is then transmitted to the software component.
Abstract:
PURPOSE: An error and distortion control method for a discharge hour meter in a wireless sensor network is provided to minimize sensor node activation period according to time by distinguishing all events in a sensor network. CONSTITUTION: Message transmission and reception time is measured between a parent sensor node(101) and a child sensor node(103). A first discharge hour meter is synchronized based on the measured transmission and reception time. The first discharge hour meter is corrected based on the result of distribution calculation for the transmission and reception time. A message including information related to a sensor node is constructed. The constructed message is transmitted and received by a sensor network. The sensor network includes the parent sensor node and the childe sensor node.
Abstract:
PURPOSE: An information transmission method of a sensor network is provided to select a short message service of a broadband network or a bearer service according to the size of transmission object information. CONSTITUTION: A gateway receives sensor network information(S310). The gateway filters, analyzes, and classifies the information(S320). The gateway generates an information report message(S330). The gateway selects a transmission service of a relay network according to the size of the information report message(S340). If an SMS(Short Message Service) of broadband network is selected, the gateway edits the information report message as an SMS message(S350,S360).
