Apparatus and method for message transmission in delay tolerant network

PURPOSE: A message transmission apparatus in a delay permission network and method thereof are provided to extend the transmission range of a message by transmitting the copy of the message to a transmission node considering of a moving speed and direction. CONSTITUTION: An information acquisition unit(120) receives a first moving vector which displays the moving direction and a current moving speed of the transmission node from a transmission node. A control unit(130) determines the transmission rate of a transmission target message copy in the copy created from the stored message based on an angle between the first moving vector and a second moving vector which displays the current moving speed and direction of the transmission node. A transmission unit(140) transmits the message copy to the transmission node.
