aims to build an integrated sensor network system for environment
surveillance on the sea. The focus of this work is to acquire and
analyze information about environment factors such as temperature, light
illuminance, sea depth, etc. Current methods are mostly
labour-intensive and the data collection lacks both the density and
consistency of samplings. By deploying a wireless sensor network, we are
able to achieve continuous surveillance on the sea environment.
with traditional land based sensor networks, most of which consist of
stationary sensor nodes, the sensor network deployed on the sea consists
of Restricted Floating Sensors (RFS), anchored to the sea bottom,
floating within a restricted area on the sea surface. The complex
impacts brought by the wind blow, tides as well as ocean currency affect
our system architecture, algorithm design and sensor node manufacture.
are deploying the working system in Tsingtao, China. We use TelosB
motes and TinyOS as our development basis. Current system consists of 20
sensor nodes deployed in the field, reporting sensing data continuously
to the base station. The complete system is designed to scale to
hundreds of sensors covering the sea area off Taipingjiao,
