OceanSense 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.
Different 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.
We 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, Tsingtao.
