DReggie: Semantic Service Discovery for M-Commerce Applications

, , , and

The emergence of mobile devices and wireless networks has created a new path in the field of e-commerce: ``m-commerce''. Significant research needs to be done in the field of service discovery to support m-commerce applications. Various new applications, that would use services available to a mobile device from both the fixed network backbone and peer mobile devices in its proximity, are being developed. M-commerce applications have the challenging task of discovering services in a dynamically changing environment. To support dynamic service discovery, existing mechanisms need to move beyond trivial attribute or interface matching. Recently the DARPA Agent Markup Language (DAML) has been developed to semantically describe the content of the web. In this paper, we describe ongoing work in developing a dynamic service discovery infrastructure using DAML. This architecture is built on the Jini service discovery framework. Our service discovery infrastructure can find services in a semantically richer way, instead of using simple attribute or interface based matching. This increased flexibility in service discovery has the potential to enable a broad range of m-commerce applications.
