Terminal-aware grid resource and service discovery and access based on agents technology

Abstract

Mobile agents can provide a suitable framework for supporting resource and service discovery in grid platforms, and can support optimal access and interaction with the user through heterogeneous terminals, differing in terms of memory capacity, computational resources, display characteristics, allowed connection mode, etc. We deal with the utilization of Web services technology to discover and optimally access mobile grid resources and services, within a mobile agent based grid architecture (MAGDA) we have designed and have been implementing. Web services paradigm and SIP and UDDI technologies are utilized to implement a resource discovery service that allow users and mobile agents to look for and access distributed resources and applications, through heterogeneous terminals, by dynamically configuring the interaction session and service functionalities based on characteristic of the terminal and QoS of the interconnection.
