UNDERWATER COMMUNICATION METHOD USING PRIORITY QUEUE

摘要

The present invention relates to an underwater communication method, more particularly to an underwater communication method using a priority queue, in which underwater information collected from a plurality of nodes is stored in a queue and data are transmitted based on the priority queue of each node. The underwater communication method according to the present invention includes: a storing step of storing underwater information data in a queue of sensor nodes by sensing the underwater information data using the sensor nodes; a first transmission step of transmitting a response message, which includes the information data stored in the queue of the sensor node, to a gateway as the sensor node receives a beacon message from the gateway; a second transmission step of allowing the gateway to transmit a scheduling message including a transmission priority to the sensor nodes after determining the transmission priority of the data based on the information stored in the queue of each sensor node; and a third transmission step of transmitting the data stored in the queue to the gateway according to the priority included in the scheduling message received in each sensor node.
