METHOD FOR ALLOCATING CHANNEL RESOURCE IN SHIP AREA NETWORK

摘要

The present invention relates to a method for allocating channel resource in a ship area network configured to efficiently guarantee a channel requested by device groups in an ECMA-392 MAC protocol. The method comprises the steps of: calculating a Fair QoD (Quality of Device group: QoD_(F,n)) at the n^th time for every device group each time a channel changes due to the movement of a device group or the change of wireless environment; transmitting the calculated QoD_(F,n) value to all device groups through beacon; and determining a reallocation method of a channel that the conventional device groups possess depending on the comparison result after the device groups which receive the beacon compare the QoD_(F,n) value to the conventional value through QoS IE.
