Grid service discovery; An approach using Parameter and QoS based matchmaking

This paper addresses the problem of discovering grid services in a heterogeneous grid environment. Our system uses semantic descriptions of grid services using the WSDL-S tool. The matchmaking algorithm used in our system uses parameter based matchmaking with inputs, outputs and functionalities to match service advertisements and requests. In case of multiple service hits for a particular service advertisement, QoS based matchmaking is used to select a service.
