Service-oriented architecture (SOA) has gained recognition due to its reusable nature of applications and interoperability between heterogeneous technologies. The basis of SOA is the service whereas service is a self-contained software module that performs a predetermined task. The most important tasks in building a service-oriented application are the creation of services with coarse-grained functionality and the creation of interfaces with the right level of abstraction that enhances service discovery and access. Dynamic Service Discovery is one of the key issues of SOA that requires new avenues of research. Agents are reusable s/w components that provide controlled/shared access to services and resources and forms the building blocks with collaborators called as collaborative agents for applications organized across various networks. This paper proposes a novel approach for a multi-agent based dynamic service discovery using matchmaking technique.
