    • Provided are a sensor node device and method for supporting mobility of a mobile node in a sensor network. The sensor node device includes: a network interface for communicating with a sink node, at least one neighboring sensor node, and the mobile node; a mobility supervisor for detecting a location of the mobile node, and deciding a sensor node for a service of a data packet received through the network interface on the basis of the detected location; a transmission decision maker for deciding a transmission mode for the data packet received through the network interface according to the location of the mobile node; and a state reporter for reporting a transmission state of the data packet through the sensor node device. When the mobile node moves to a place where radio wave propagation areas of sensor nodes overlap each other, the radio wave intensity of each sensor node is detected to perform a handoff to the sensor node of the area having the strongest radio wave intensity. Thus, a ping-pong problem caused by unnecessary repeated handoff, and a delay problem caused by too slow handoff, can be prevented.
    • 提供了一种用于支持传感器网络中的移动节点的移动性的传感器节点设备和方法。 传感器节点设备包括:用于与汇聚节点,至少一个相邻传感器节点和移动节点通信的网络接口; 用于检测所述移动节点的位置的移动性管理器,以及基于所述检测到的位置,通过所述网络接口确定用于服务接收到的数据分组的传感器节点; 传输决策器,用于根据移动节点的位置来决定通过网络接口接收的数据分组的传输模式; 以及状态报告器,用于通过传感器节点设备报告数据分组的传输状态。 当移动节点移动到传感器节点的无线电波传播区域彼此重叠的位置时,检测每个传感器节点的无线电波强度,以对具有最强无线电波强度的区域的传感器节点进行切换。 因此,可以防止由不必要的重复切换引起的乒乓问题,以及由于切换过慢造成的延迟问题。
