DYCE (2009-2011)

The DYCE consortium worked to develop a capability for the rapid deployment of sensors to gather data on chemical agents following their malicious or accidental release into an outdoor (industrial/urban) environment. The validity of chemical composition measurements is reliant upon the ability to gather air samples that are representative of the whole environment. To build an accurate picture of this it is currently necessary to deploy large quantities of chemical sensors, which is prohibitively time consuming and expensive. DYCE aimed to mitigate this limitation through the development of deployment planning tools that react to gathered data and instruct the dynamic redeployment of a limited set of wireless sensor nodes, thereby optimising their data gathering capability.

The system employs a small network of ad-hoc deployable sensor nodes that are able to monitor and react to changing local conditions and chemical data content to enable end-users to dynamically optimise their locations. The solution is novel in that it addresses the combined issues of:

1. Optimised data gathering through intelligent organisation of the sensor network.

2. Monitoring localised changing environmental conditions and understanding its repercussions on the data-gathering mission.

3. Operating effectively in EM cluttered and complex urban and industrial environments by incorporating wireless communications needs into the deployment strategy.

4. Developing a deployment planning solution to optimise the data gathering mission given a constrained or unconstrained asset base.
