On-Line Image Gathering Utilizing an Operated Underwater Movable Sensor Node

The aim of our current research is to deploy a wireless sensor network for observing and collecting data on underwater environments. This paper describes the development of an underwater environment data collection system with a movable sensor node, and it details underwater data observation and collection experiments. Owing to their mobility, movable underwater sensor node can contribute to observation and to the collection of environmental data in small and hidden locations. The systemwe develop, with itsmovable sensor node platform, uses a mounted camera on a wireless network to capture underwater images. Collection experiments for the on-line underwater images with timestamps are carried out using the prototype system. Captured images with timestamps are sent to the host computer via a wireless network while the movable node is operated for the mission. In this paper, our fundamental attempts are discussed and collected data in the experiment are also shown as results.
