PURPOSE: A communication method for a mobile sensor node in a wireless sensor network is provided to select one of sensor nodes of a wireless sensor network as a parents node, thereby communicating with the selected parent node. CONSTITUTION: A mobile sensor node transmits a message to a parents sensor node during a transmission interval of a downward active interval(218,220,222). The mobile sensor node checks whether a message is received from the parents sensor node during a receiving interval of the downward active interval(224). If a message is not received from the parents sensor node, the mobile sensor node is reset as a parents sensor node(228). If the message is received from the parents sensor node, the mobile sensor node performs time-synchronization by a message reception interrupt from the parents sensor(226).
