Characteristics of wireless sensor network for full-scale ship application

Abstract

In this study, basic experiments regarding the wireless sensor network were conducted on a 3,000-ton-class training ship as the first step in applying the ubiquitous technology to a real ship. Various application fields of the technology in terms of the provision of safety and convenience on a ship were identified through these experiments. To efficiently adopt the ubiquitous technology for ship application, it is necessary to identify the state-of-the-art ubiquitous technology and to prepare countermeasures against the harsh environment of a ship. The characteristics of the wireless sensor network were investigated on a test bed ashore as well as on a real ship before full-scale ship application. In particular, experimental results concerning communication depth, data transmission ratio, and battery consumption in a sensor node are described in detail.
