Mobile agents based infrastructure for Web Services composition

Web services (WSs) are emerging as a major technology to enable dynamic service discovery, composition, and invocation. Although WSs are convenient in integrating and interoperating among applications, the functionalities of individual WS are limited and cannot satisfy some practical user requirements. The true potential can be achieved if WSs are used to dynamically compose some existing/new WSs. Moreover, WS technology is to be applied in various environments, such as wireless networks of relatively narrow bandwidth and unstable connections. In response to the mentioned problems we adopt mobile agent technology and present a mobile agent framework for WSs integration. We exploit the capabilities offered by mobile agents to invoke WSs without the need for simultaneous presence of the service requestor.
