<p>The present invention relates to an enhanced ad-hoc self-organizing time division multiple access (EASO-TDMA) type media access control method for a 2nd generation modem, comprising a first phase (FP) processing step including network entry, time slot scanning, neighboring ship (NS) checking, and path setting, and a normal phase (NP) processing step of transmitting a packet during an occupied time slot using a given path and receiving packets of neighboring ships during the other times. According to the present invention, since the number of time slots of a ship is set according to the number of transmission nodes by using a route table, and a time slot is allocated to communicate to a destination during one frame, a transmission delay time can be reduced and occurrence of an application timeout can be prevented, and thus, wireless communication with a land based station, as well as communication between marine neighboring ships, can be more stably performed.</p> |
