A Simulation Study of Effect of Fish Body Size on Communication Performance in a Fish Farm Monitoring Environment

In recent years, sensor network technologies have attracted attentions in the field of the primary industry such as the aquaculture industry. We have proposed a fish farm monitoring system for developing efficient farming of tuna. In our monitoring system, a sensor node is attached at fish and its sensing data are gathered at a sink node. In the monitoring environment, the size of fish is varied between 5 cm and 100 cm depending on the age of fish. Therefore, the communication environment is also varied depending on the age. In this paper, we investigate the effect of fish body size on the performance of communication in our monitoring system. Through simulation evaluations, we show that the size of fish significantly affects to the data gathering performance.
