APPARATUS AND METHOD FOR MESSAGE TRANSMISSION IN DELAY TOLERANT NETWORK CONSIDERING THE CHARACTERISTICS OF PACKET

摘要

A message transmission device in a delay allowance network considering packet characteristics and a message transmission method are disclosed. A message classification unit classifies messages into predetermined packets according to the predetermined standard. A transmission possibility modification unit calculates a modification transmission possibility value in which a first transmission possibility modification value is modified in order to transmit the message from a transmission node to a destination node. A message transmission unit transmits the message from the transmission node to the reception node when the predetermined condition is satisfied by comparing a second transmission possibility value with the modified transmission possibility value. The present invention can improve a service quality by considering the packet characteristics and transmission possibility defined based on the touch information with the destination node in the PRoPHET protocol of the delay allowance network.
