A Method for Gathering Sensor Data for Fish-Farm Monitoring Considering the Transmission-Range Volume

Koichi ISHIDA, Yoshiaki TANIGUCHI, Nobukazu IGUCHI
2018 IEICE transactions on information and systems  
In this letter, we propose a data-gathering method for fish-farm monitoring without the use of control packets so that energy-efficient control is possible.  ...  Instead, our method uses the transmission-range volume as calculated from the location of the sensor node to determine the timing of packet transmission.  ...  Acknowledgments This work was partly supported by JSPS KAKENHI grant number 16K00146 of Japan.  ...
