    • A sensor network system and method for establishing a data transmission path are is disclosed. The method for establishing a data transmission path of a sink node and the network system which includes a plurality of nodes including the sink node, includes a) requesting nodes on a previously established data transmission path to give their adjacent node information, b) receiving the adjacent node information, c) retrieving adjacent nodes as the sink node moves, and d) reestablishing the data transmission path through the result of retrieval and the adjacent node information. Since the data transmission path isreestablished without flooding, it is possible to reduce energy of the nodes. Also, the method for establishing a data transmission path can be applied to any routing protocols without additional conditions.
    • 公开了一种用于建立数据传输路径的传感器网络系统和方法。 用于建立宿节点的数据传输路径的方法和包括多个包括宿节点的节点的网络系统的方法包括:a)在先前建立的数据传输路径上请求节点以给出其相邻节点信息,b)接收 相邻节点信息,c)当宿节点移动时检索相邻节点,以及d)通过检索结果和相邻节点信息重新建立数据传输路径。 由于数据传输路径是建立在没有洪泛的情况下,可以减少节点的能量。 此外,用于建立数据传输路径的方法可以应用于任何路由协议而没有附加条件。

    • Multimedia contents moving method and system. In a multimedia system including a media server for transmitting media data, at least one multimedia device for playing the media data and at least one controller for controlling the multimedia device, the method includes the steps of: sending a copy command to a first multimedia device using the controller; sending the copy command to the media server from the first multimedia device; sending a play-stop command to the first multimedia device from the multimedia server; storing a current play location of the multimedia data by the media server; sending a paste command from the controller to a second multimedia device so as for the second multimedia device to play the later part of the multimedia data which was being played by the first multimedia device, and sending the paste command from the second multimedia device to the media server; and transmitting the media data from the media server to the second multimedia device. A user can continuously use the multimedia contents using different kinds of multimedia devices by simply operating a controller while moving around, that is, moving from a place to a different place, in a home network system, even in a case where the user moves from a place to a different place.
    • 多媒体内容移动方法和系统。 在包括用于传送媒体数据的媒体服务器的多媒体系统中,至少一个用于播放媒体数据的多媒体设备和至少一个用于控制多媒体设备的控制器,该方法包括以下步骤:向第一多媒体设备发送复制命令 使用控制器; 从所述第一多媒体设备向所述媒体服务器发送所述复制命令; 从多媒体服务器向第一多媒体设备发送播放停止命令; 通过媒体服务器存储多媒体数据的当前播放位置; 从所述控制器发送粘贴命令到第二多媒体设备,以使所述第二多媒体设备播放由所述第一多媒体设备正在播放的所述多媒体数据的后续部分,以及将所述粘贴命令从所述第二多媒体设备发送到 媒体服务器 以及将所述媒体数据从所述媒体服务器发送到所述第二多媒体设备。 即使在用户从家庭网络中移动的情况下,用户也可以通过简单地在家庭网络系统中移动周围移动控制器(即,从一个地方移动到另一个地方)来连续地使用不同种类的多媒体设备的多媒体内容 一个地方到不同的地方。
