    摘要: Provided are an energy-efficient communication method in a group information-based sensor network and a sensor network system using the method. A group exchanges group information and data with another group in order to provide an application service through inter-group cooperation in a sensor network. In this process, a target group is discovered, a communication path is established, and inter-group communication cycle information for energy-efficient communication is transmitted. On the basis of the group information and the communication cycle information, it is possible to minimize the network resource consumption and provide an energy-efficient inter-group communication method.

    摘要: Disclosed herein are an apparatus and method for acquiring 3D depth information. The apparatus includes a pattern projection unit, an image acquisition unit, and an operation unit. The pattern projection unit projects light, radiated by an infrared light source, into a space in a form of a pattern. The image acquisition unit acquires an image corresponding to the pattern using at least one camera. The operation unit extracts a pattern from the image, analyzes results of the extraction, and calculates information about a 3D distance between objects existing in the space.

    摘要: Disclosed are an apparatus and a method for smart energy management by controlling power consumption. Power consumption information is collected from one or more electrical device groups with a smart meter and electrical devices connected through gateways. When the method estimates that the power consumption will be larger than a threshold value, a control command is outputted to a load controller connected through the gateway and power consumption of electrical devices that belong to the electrical device using group is remotely controlled. According to an embodiment of the present invention, an energy company that produces and supplies energy can supply energy depending on a consumer's demand by using current facilities because the present invention can collect remotely energy consumption, analyze energy consumption patterns, and control automatically the energy consumption of electrical devices installed in a customer's area. The consumer who consumes energy can save the energy consumption and the charge of the energy consumption.

    摘要: A method and apparatus for provisioning a node with executable code is provided herein. Prior to sending out a code request, a node (101) determines a set of nodes that may potentially host the requested code and sends the request to these nodes instead of a blind broadcast. The determination of what nodes have access to the required code is based on a history information of code request of the node, the overhead traffic, and/or application dependencies that are available to the node. The code request is unicast-based and may involve a multi-hop path for both code requests and responses. If this step fails, a broadcast-based approach can be again employed to request the code.
