Abstract—The Universal Network, which promises pervasive services, is well on the way. As the Quality of Service (QoS) grading is a significant feature of the Universal Network, various pervasive services can be distinguished not only by service types, but also by QoS. This characteristic makes service discovery of the Universal Network quite distinct from that of the existing network. A lot of research work takes advantage of the semantic web technology OWL-S (Web Ontology Language for Services) to achieve service discovery. In this work, we propose to append the QoS measurements to OWL-S (named OWLQoS) to describe pervasive services. Related matching algorithms are also presented. Moreover, we employ the JXTA architecture, which is a suitable foundation to build the future computer systems, to organize network peers and implement a P2P based service discovery prototype system. Experiments highlight the good performance of the P2P based semantic service discovery with QoS measurements.
