FloodNet is a UK project sponsored by the Department of Trade and Industry. Its mission is to develop methods to monitor flood levels through the use of pervasive computing technologies. These are initially being tested on a tidal estuary in the UK which is subject to daily tidal flooding.
The FloodNet system architecture uses a network based on the IEEE specification 802.11 for wireless LAN technologies. Each node consists of an embedded computer mounted on a post in the estuary. The nodes measure the water level at regular intervals and transmit the data over the network to a micro broker running on a customized node called the gateway node. The data is consolidated and subsequently transmitted over GPRS to a central WebSphere
® Message Broker where the sensor data is transformed and delivered to any application that subscribes to the data.
The sensor data is used for various applications such as simulation models, GIS Visualization and archiving. Using the publish and subscribe model, additional applications can be developed that make use of the same data. Also, additional sensors could be added to the nodes, to measure say air pressure, and the data flowed back through the brokers without disrupting existing applications. The intent is to create a suite of applications that can accurately monitor, model, analyze and predict the state of rivers so that agencies and the media can be notified on a timely basis when flooding is likely to occur.
