Abstract: PURPOSE: A distributional media access control protocol based vessel logistics system is provided to solve the problem that information of an RFID reader is not able to be transmitted to a vessel logistics system server due to inconsistency of the communication standard when an RFID mounted in a container for vessel logistics moves to a vessel logistics warehouse in other region. CONSTITUTION: A super frame is divided into a BP(Beacon Period) and a DTP(Data Transfer Period). The BP is divided into a plurality of small beacon time slots to transmit their own beacon frame. The representative IE(Information Element) capable of transmitting in a beacon frame is a DRP(Distributed Reservation Protocol) IE and a DRP Availability IE and exchanges resource reservation information and control information using a DRP IE and a DRP Availability IE and reserve resources.
