    • 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.
