Designing a Novel SOA Architecture for Security and Surveillance WSNs with COTS
Mario Lopez-Ramos, Jérémie Leguay, Vania Conan · 2007
We consider the challenge of enhancing sensor networks for surveillance and global security with increased distributed data processing capabilities, including multi-sensor fusion, data aggregation or mining, and rule-based alert generation. We advocate a novel architecture that will enable the creation of more resilient and complex monitoring applications. We exemplify its benefits in a chemical accident scenario. The architecture introduces new processing nodes in the field and derives the requirements for the software they will run. We propose to consider the use of a service oriented architecture (SOA) to program and deploy the data processing applications. We analyze existing and on-going work within the Web Services community and conclude that it is possible to implement the architecture with an appropriate combination of COTS (commercial off-the-shelf software components). We conclude with our plans to move forward in this direction and validate the approach on a hardware and software testbed.
