The authors proposed the development of the environmental observation network in the Toyama bay which is the application of a coast ubiquitous sensor network. Conventionally, coast environmental monitoring had complicated measurement and analytical work. Then, we tried to carry out network connection of the sensor buoys in order to observe two or more points in a real-time. The communication between coordinator routers was possible as a result of the communication experiment with a marine small boat and a land base station. Between the base station and the coordinator buoy, the receiving rate of 19.3[%] was obtained with the range 1[km]. However, the measured receiving rate had deteriorated remarkably for the influence of an obstacle. Finally, the buoy for sensor networks was made as an experiment and evaluated.
