Discovering services from mobile terminal by means of peer-to-peer networking and semantic descriptions

This paper deals with application of P2P technology and semantic description of services in solving the problem of discovering Internet services from a mobile terminal. As a solution to this problem, we propose the system named Semantic Web Services Discovery (SWSD). This system is based on P2P technology, semantic description of Internet services, and access from a mobile terminal. The JXTA P2P platform is chosen as an implementation of P2P technology, and DAML-S is chosen for semantic description of services. This paper elaborates the architecture and implementation of SWSD system. The runtime operation of the system is verified through the case study of finding the stock exchange information on the Internet from a mobile terminal.
