In this paper, we describe TinyObj service discovery model, which uses short wireless packet broadcasts for service discovery within a user’s vicinity. We present a prototype implementation for the discovery model including the hardware and software development of a wireless discovery device. The developed wireless device, called Buoy, can be used as an independent service discovery device or a...

The availability of cheap wireless technologies, which can be interconnected through the Internet, has paved the way to a large fruition of (web) services and the convergence of the Internet with mobile handheld devices. A potential market opportunity could become concrete only if users can easily locate and access the available services, thorough support for Service Discovery. There are a numb...

Service discovery and delivery problems have recently been drawing much attention from researchers and practitioners. SLP, Jini, and UPnP are among the few emerging service discovery protocols. Although they seem to provide a good solution to the problem, there is an unaddressed need of more sophisticated location and context-aware service selection, and mobile device support. In this paper, we...

In this paper we propose an architecture for modeling the service discovery functionality of computing devices operating in pervasive computing environments. Forming wireless ad hoc networks requires service discovery protocols that support both proximity-based detection and abstract level service matching. In the proposed architecture, services, provided by sensors and actuators, are indirectl...

Service discovery problem has recently been drawing much attention from researchers and practitioners. Jini, SLP, and UPnP are among the few emerging service discovery protocols. Although they seem to provide a good solution to the problem, there is an unaddressed need of more sophisticated location and context-aware service selection support. In this paper, we introduce the concept of context ...

The Web Service Modeling Ontology (WSMO) provides a conceptual framework for semantically describing Web services and their specific properties. In this chapter we discuss how WSMO can be applied for service discovery. We provide a proper conceptual grounding by strictly distinguishing between service and Web service discovery and then present different techniques for realizing Web service disc...

Semantic web services promise to add automation and dynamics to current web service technologies, considerably reducing the effort required to integrate applications, businesses and customers. One of the key tasks in the integration process is to locate services that can fulfill the application, business or customer needs. With current web service technologies, this is done mainly manually, whi...

The service of Universal Network is distinct from that of current network in that the former has QoS (Quality of Service) grading, and as a result, service discovery in the Universal Network is also quite different from that of present network. In this paper, we present a hierarchical semantic service discovery system for the Universal NetworkUniNServ. It uses OWL-S (Web ontology language for s...

Key challenges in wireless mobile ad hoc networks are computational resource constraints, power limitations, and efficient service discovery techniques. The short range radio network technology Bluetooth suffers from long service discovery delays and high power consumption due to necessary connection establishment between discovering and discovered entity. For improving the efficiency of servic...

With the increasing adoption of Web Services and service-oriented computing paradigm, matchmaking of web services with the request has become a significant task. This warrants the need to establish an effective and reliable Web Service discovery. Here reducing the service discovery time and increasing the quality of discovery are key issues. This paper proposes a new semantic Web Service discov...
