Exploiting extreme heterogeneity in a flood warning scenario using the Gridkit middleware

ABSTRACT

This demonstration showcases the Gridkit middleware in a flood monitoring and warning scenario. Gridkit provides the services required to support wireless sensor network based environmental monitoring and also hosts lightweight hydraulic models which are used to provide timely alerts to local residents warning of imminent flood events. In this scenario, Gridkit abstracts over a number of low-level sensing, computational and networking technologies. This paper and associated demonstration will show that using distributed dynamic reconfiguration, these heterogeneous sensor network technologies may be safely adapted to cope with changing environmental conditions while providing timely flood warnings, resulting in significant power savings and performance improvements.
