An effective middleware based architecture for discovering web services on Mobile devices

In Today's world Mobile devices are the important handheld devices spreading throughout the world, and it is necessary to integrate web services into the mobile device. We introduce a simple approach for dynamically invoking web service methods from mobile devices with minimal user intervention that only involves entering a search phrase and values for the method parameters. This energy efficient architecture overcomes technical challenges that involve power consuming and speedy access of web services by introducing man-in-the-middle (MIM) server that provides a web service whose responsibility is to discover needed services and build the client-side proxies at runtime. We perform extensive evaluations of the system performance to measure scalability as it relates to the capacity of the MIM server in handling mobile client requests, and device battery power savings resulting from delegating the service discovery tasks to the server.
