Architecture for Application Development on the fly for Wireless Sensor Networks

Wireless sensor networks are designed and built as per the application´s needs and thus cannot be shared by other applications. This makes the deployment of applications expensive and the applications are always built after the initial event. The authors propose and explain the novel concept of application development on the fly and propose the architecture for such a system. They also propose a strategy for the reuse of the elements of the pre-existing application networks, by the new application under development. The application development in real time when the event is taking place, assumes the availability of the base knowledge needed for the network somewhere on the net or the availability of human expert. The proposed architecture uses the following concepts: semantic interpretation of low level signals reaching an application server, identification of the problem, problem decomposition on the fly, identifying SW agents that could solve sub problems and integrate the sub problem solutions into the complete solution. It makes use of distributed knowledgebases across the net and data- mining techniques. The paper identifies the major challenges in developing such systems.
