As sensor networks mature, there will be an increasing need for re-usable, dynamically taskable software systems that support multiple concurrent applications. In this paper, we c...
In a service-oriented architecture, systems communicate by exchanging messages. In this work, we propose a formal model based on OCL-constrained UML Class diagrams and a methodolo...
Visualization techniques have proven to be critical in helping crime analysis. By interviewing and observing Criminal Intelligence Officers (CIO) and civilian crime analysts at th...
—PlanetLab is a globally distributed overlay platform that has been increasingly used by researchers to deploy and assess planetary-scale network services. This paper analyzes so...
Distributed sensor networks offer many new capabilities for contextually monitoring environments. By making such systems mobile, we increase the application-space for the distribut...
