A Method for Gathering Sensor Data from Farmed Fish under Limited Transmission Range Condition

e have proposed a fish farm monitoring system for efficient farming of fish. In our system, sensor nodes are attached at fish to monitor health status. In this paper, we propose a method for gathering data of sensor nodes to a sink node under limited transmission range condition. In our proposed method, a part of sensor nodes become leader nodes with a certain probability. A leader node gathers data from its neighbor sensor nodes and sends gathered data to its neighbor leader node heading for the sink node. In addition, a leader node sends its gathered data to the sink node when it is closer to the sink node. Through simulation evaluations, we show the basic performance of our proposed method
